birth-up values Run profound in their DNA, says Steve Daheb, Senior vice-president, Oracle Cloud | killexams.com existent Questions and Pass4sure dumps

India is a key boom financial system and a essential marketplace for Oracle. “we're dedicated to India and are helping a number of clients of their adventure to cloud,” Steve Daheb, senior vice-president, Oracle Cloud, tells Sudhir Chowdhary in a recent interview. Excerpts:

What were your observations on the evolution of cloud in the closing 2-three years?

instead of ‘why cloud’, customers at the moment are asking ‘how’. They possess an interest in greater understanding a route to achieve the mission-vital migration seamlessly. The dialog has shifted to being facts centric—analytics, securing the statistics, placing information to more desirable use with laptop gaining knowledge of. I accept as exact with they are in a very respectable position to pressure the next wave of business cloud adoption.

inform us concerning the updates on your ordinary cloud enterprise.

For us it's vital to tackle utter layers of the stack, from purposes which are tied intently to their structures, which are linked to these purposes to Run analytics round them, to comfy them and prolong their capabilities to the underlying infrastructure. This makes it possible for their shoppers to Run excessive performance workloads easily, whereas moreover decreasing cost.

10 SQL hints that you simply didn’t suppose had been feasible | killexams.com existent Questions and Pass4sure dumps

This save up was at first published over at jooq.org, a weblog focusing on utter issues open supply, Java and application building from the perspective of jOOQ.

Listicles enjoy these achieve work – now not handiest achieve they attract attention, if the content is additionally useful (and in this case it is, possess faith me), the article format can moreover live extremely unique.

this article will bring you 10 SQL tricks that lots of you might not possess faith had been feasible. The article is a abstract of my new, extremely fast-paced, ridiculously childish-humored talk, which I’m giving at conferences (currently at JAX, and Devoxx France). You can moreover quote me on this:

the total slides can moreover live seen on SlideShare:

… and i’m bound there’ll live a recording on video quickly. listed below are 10 SQL tricks that you just Didn’t feel had been feasible:

Introduction

in an exertion to possess in intelligence the value of these 10 SQL hints, it is first crucial to possess in intelligence the context of the SQL language. Why achieve I talk about SQL at Java conferences? (and that i’m continually the only one!) here's why:

sql-tricks-slide-006

From early days onwards, programming language designers had this exigency to design languages during which you relate the machine WHAT you exigency in consequence, no longer a route to achieve it. as an example, in SQL, you inform the machine that you just exigency to “connect” (be a section of) the person desk and the address desk and locate the clients that reside in Switzerland. You don’t keeping HOW the database will retrieve this assistance (e.g. may soundless the users desk live loaded first, or the tackle desk? may soundless the two tables live joined in a nested loop or with a hashmap? should soundless utter statistics live loaded in reminiscence first and then filtered for Swiss users, or should soundless they handiest load Swiss addresses within the first place? and so on.)

As with every abstraction, you are going to nevertheless should recognize the fundamentals of what’s happening in the back of the scenes in a database to wait on the database fabricate the commandeer decisions if you query it. as an instance, it makes sense to:

  • establish a proper peculiar key relationship between the tables (this tells the database that every tackle is guaranteed to possess a corresponding consumer)
  • Add an index on the search field: The country (this tells the database that particular countries may moreover live present in O(log N) instead of O(N))
  • but as soon as your database and your software matures, you can possess save utter of the essential meta information in area and you can focus in your enterprise logic only. here 10 tricks present unbelievable performance written in exactly a few traces of declarative SQL, producing basic and moreover complicated output.

    1. everything is a desk

    this is probably the most trivial of hints, and not even truly a trick, but it surely is simple to an intensive figuring out of SQL: every dinky thing is a table! in case you behold a SQL remark enjoy this:

    choose * FROM person

    … you are going to promptly spot the desk grownup sitting commandeer there in the FROM clause. That’s cool, it truly is a table. but did you realize that the entire statement is additionally a desk? as an instance, that you may write:

    choose * FROM ( opt for * FROM adult ) t

    And now, you've got created what is referred to as a “derived table” – i.e. a nestedSELECT statement in a FROM clause.

    That’s trivial, but if you deem of it, rather elegant. that you would live able to moreover create advert-hoc, in-memory tables with the VALUES() constructor as such, in some databases (e.g. PostgreSQL, SQL Server):

    opt for * FROM ( VALUES(1),(2),(three) ) t(a)

    Which effortlessly yields:

    If that clause isn't supported, you can revert to derived tables, e.g. in Oracle:

    opt for * FROM ( opt for 1 AS a FROM twin UNION ALL select 2 AS a FROM twin UNION ALL select 3 AS a FROM dual ) t

    Now that you just’re on account that VALUES() and derived tables are definitely the same thing, conceptually, let’s evaluate the INSERT observation, which is available in two flavors:

    -- SQL Server, PostgreSQL, some others: INSERT INTO my_table(a) VALUES(1),(2),(three); -- Oracle, many others: INSERT INTO my_table(a) select 1 AS a FROM twin UNION ALL opt for 2 AS a FROM dual UNION ALL opt for 3 AS a FROM dual

    In SQL every thing is a table. for those who’re inserting rows perquisite into a table, you’re not really inserting individual rows. You’re in fact inserting complete tables. Most people just swirl up to insert a single-row-desk many of the time, and consequently don’t recognize what INSERT in reality does.

    every dinky thing is a desk. In PostgreSQL, even functions are tables:

    opt for * FROM substring('abcde', 2, 3)

    The above yields:

    if you’re programming in Java, that you would live able to use the analogy of the Java eight stream API to assume this one step extra. believe here equal ideas:

    table : circulate<Tuple<..>> select : map() diverse : diverse() be a section of : flatMap() where / HAVING : filter() community with the aid of : assemble() ORDER by using : sorted() UNION utter : concat()

    With Java 8, “everything is a flow” (as soon as you delivery working with Streams, at least). No signify the route you transform a stream, e.g. with map() or filter(), the ensuing ilk is at utter times a rush again.

    We’ve written a whole article to interpret this extra deeply, and to compare the rush API with SQL:standard SQL Clauses and Their Equivalents in Java 8 Streams

    And in case you’re attempting to find “greater streams” (i.e. streams with much more SQL semantics), achieve check out jOOλ, an open source library that brings SQL window functions to Java.

    2. statistics era with recursive SQL

    general desk Expressions (also: CTE, moreover referred to as subquery factoring, e.g. in Oracle) are the best solution to declare variables in SQL (apart from the imprecise WINDOW clause that simplest PostgreSQL and Sybase SQL anyplace know).

    this is a powerful theory. extremely powerful. faith perquisite here remark:

    -- desk variables WITH t1(v1, v2) AS (opt for 1, 2), t2(w1, w2) AS ( select v1 * 2, v2 * 2 FROM t1 ) select * FROM t1, t2

    It yields

    v1 v2 w1 w2 ----------------- 1 2 2 four

    the usage of the basic WITH clause, that you would live able to specify a list of table variables (bear in mind: every dinky thing is a desk), which may even reckon on each and every different.

    it's effortless to uphold in mind. This makes CTE (typical desk Expressions) already very valuable, however what’s in fact basically astonishing is that they’re allowed to live recursive! faith the following PostgreSQL instance:

    WITH RECURSIVE t(v) AS ( select 1 -- Seed Row UNION ALL select v + 1 -- Recursion FROM t ) select v FROM t restrict 5

    It yields

    v—12345

    How does it work? It’s surprisingly convenient, once you behold during the many keywords. You define a benchmark table expression that has exactly two UNION utter subqueries.

    the primary UNION utter subquery is what I continually title the “seed row”. It “seeds” (initialises) the recursion. it may produce one or a brace of rows on which they can recurse afterwards. live aware: every thing is a desk, so their recursion will occur on a whole desk, no longer on a person row/value.

    The second UNION utter subquery is the situation the recursion occurs. in case you issue closely, you will observe that it selects from t. I.e. the 2d subquery is allowed to select from the very CTE that we’re about to declare. Recursively. It therefore has moreover access to the column v, which is being declared through the CTE that already uses it.

    In their example, they seed the recursion with the row (1), and then recurse by means of including v + 1. The recursion is then stopped at the use-web page with the aid of atmosphere aLIMIT 5 (beware of doubtlessly endless recursions – just enjoy with Java 8 Streams).

    facet notice: Turing completeness

    Recursive CTE fabricate SQL:1999 turing comprehensive, which capability that any program can moreover live written in SQL! (if you’re crazy enough)

    One awesome illustration that frequently shows up on blogs: The Mandelbrot Set, e.g. as displayed on http://explainextended.com/2013/12/31/satisfied-new-12 months-5/

    WITH RECURSIVE q(r, i, rx, ix, g) AS ( opt for r::DOUBLE PRECISION * 0.02, i::DOUBLE PRECISION * 0.02, .0::DOUBLE PRECISION , .0::DOUBLE PRECISION, 0 FROM generate_series(-60, 20) r, generate_series(-50, 50) i UNION ALL select r, i, CASE WHEN abs(rx * rx + ix * ix) &amp;amp;lt;= 2 THEN rx * rx - ix * ix conclusion + r, CASE WHEN abs(rx * rx + ix * ix) &amp;amp;lt;= 2 THEN 2 * rx * ix halt + i, g + 1 FROM q the situation rx is not NULL AND g &amp;amp;lt; 99 ) select array_to_string(array_agg(s ORDER with the aid of r), '') FROM ( select i, r, substring(' .:-=+*#%@', max(g) / 10 + 1, 1) s FROM q group with the aid of i, r ) q group by means of i ORDER by using i

    Run the above on PostgreSQL, and moreover you’ll net whatever thing like

    .-.:-.......==..*.=.::-@@@@@:::.:.@..*-. =. ...=...=...::+%.@:@@@@@@@@@@@@@+*#=.=:+-. ..- .:.:=::*....@@@@@@@@@@@@@@@@@@@@@@@@=@@.....::...:. ...*@@@@=.@:@@@@@@@@@@@@@@@@@@@@@@@@@@=.=....:...::. .::@@@@@:-@@@@@@@@@@@@@@@@@@@@@@@@@@@@:@..-:@=*:::. .-@@@@@-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@.=@@@@=..: ...@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@:@@@@@:.. ....:-*@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@:: .....@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@-.. .....@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@-:... .--:+.@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@... .==@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@-.. ..+@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@-#. ...=+@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@.. -.=-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@..: .*%:@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@:@- . ..:... ..-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ .............. ....-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@%@= .--.-.....-=.:..........::@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@.. ..=:-....=@+..=.........@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@:. .:+@@::@==@-*:%:+.......:@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@. ::@@@-@@@@@@@@@-:=.....:@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@: .:@@@@@@@@@@@@@@@=:.....%@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ .:@@@@@@@@@@@@@@@@@-...:@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@:- :@@@@@@@@@@@@@@@@@@@-..%@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@. %@@@@@@@@@@@@@@@@@@@-..-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@. @@@@@@@@@@@@@@@@@@@@@::+@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@+ @@@@@@@@@@@@@@@@@@@@@@:@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@.. @@@@@@@@@@@@@@@@@@@@@@-@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@.

    incredible, huh?

    three. running total Calculations

    This blog is filled with running complete examples. They’re probably the most most academic examples to study superior SQL, as a result of there are at the least a dozen of ways the route to save in force a operating total.

    A working total is effortless to assume note, conceptually.

    eder 1

    In Microsoft Excel, you may readily calculate a sum (or change) of two customary (or subsequent) values, after which use the beneficial crosshair cursor to drag that system via your whole spreadsheet. You “run” that total through the spreadsheet. A “running total”.

    In SQL, the greatest solution to try this is through the use of window functions, a further theme that this blog has covered many time and again.

    Window services are an impressive thought – now not so effortless to possess in intelligence at the beginning, however basically, they’re basically actually handy:

    Window services are aggregations / rankings on a subset of rows relative to the current row being transformed by using select

    That’s it.:)

    What it very nearly talent is that a window feature can accomplish calculations on rows which are “above” or “under” the current row. unlike ordinary aggregations and community with the aid of, although, they don’t transform the rows, which makes them very valuable.

    The syntax can live summarized as follows, with particular person constituents being non-compulsory

    characteristic(...) OVER ( PARTITION by means of ... ORDER by means of ... ROWS BETWEEN ... AND ... )

    So, we've any sort of feature (we’ll behold examples for such features later), adopted with the aid of this OVER() clause, which specifies the window. I.e. this OVER()clause defines:

  • The PARTITION: best rows that are in the identical partition as the latest row will live regarded for the window
  • The ORDER: The window can live ordered independently of what we’re deciding on
  • The ROWS (or range) carcass definition: The window can moreover live restrained to a set volume of rows “ahead” and “in the back of”
  • That’s utter there is to window services.

    Now how does that assist us calculate a working total? accept as exact with here records:

    | identity | VALUE_DATE | quantity | poise | |------|------------|--------|------------| | 9997 | 2014-03-18 | 99.17 | 19985.eighty one | | 9981 | 2014-03-sixteen | 71.44 | 19886.64 | | 9979 | 2014-03-sixteen | -ninety four.60 | 19815.20 | | 9977 | 2014-03-16 | -6.ninety six | 19909.80 | | 9971 | 2014-03-15 | -sixty five.95 | 19916.seventy six |

    Let’s anticipate that stability is what they exigency to calculate from volume

    Intuitively, they will instantly behold that perquisite here holds genuine:

    sql-tricks-slide-081

    So, in undeniable English, any steadiness will moreover live expressed with perquisite here pseudo SQL:

    TOP_BALANCE – SUM(volume) OVER (“all the rows on proper of the current row”)

    In precise SQL, that could then live written as follows:

    SUM(t.amount) OVER ( PARTITION by means of t.account_id ORDER by route of t.value_date DESC, t.id DESC ROWS BETWEEN UNBOUNDED preceding AND 1 preceding )

    rationalization:

  • The partition will calculate the sum for each checking account, now not for the whole information set
  • The ordering will fabricate positive that transactions are ordered (inside the partition) earlier than summing
  • The rows clause will harmonize with only previous rows (within the partition, given the ordering) ahead of summing
  • All of this may occur in-reminiscence over the information set that has already been chosen through you to your FROM .. where and so on. clauses, and is hence extremely fast.

    Intermezzo

    before they rush on to the entire other dazzling hints, faith this: We’ve considered

  • (Recursive) typical table Expressions (CTE)
  • Window services
  • each of those points are:

  • staggering
  • Exremely potent
  • Declarative
  • a section of the SQL ordinary
  • accessible in most accepted RDBMS (apart from MySQL)
  • Very valuable constructing blocks
  • If anything can live concluded from this text, it's the proven fact that you'll want to completely know these two constructing blocks of contemporaneous SQL. Why? as a result of:

    four. finding the largest collection and not using a gaps

    Stack Overflow has this very fine feature to inspire people to dwell on their website for as long as feasible. Badges:

    sql-tricks-slide-090

    For scale, that you could behold how many badges I actually have. heaps.

    How achieve you calculate these badges? Let’s possess a glance on the “fanatic” and the “Fanatic”. These badges are awarded to any person who spends a given quantity of consecutive days on their platform. inspite of any wedding date or wife’s birthday, you must LOG IN, or the counter begins from zero again.

    Now as we’re doing declarative programming, they don’t keeping about keeping any status and in-reminiscence counters. They are looking to specific this in the variety of on-line analytic SQL. I.e. deem this statistics:

    | LOGIN_TIME | |---------------------| | 2014-03-18 05:37:13 | | 2014-03-sixteen 08:31:forty seven | | 2014-03-16 06:eleven:17 | | 2014-03-16 05:59:33 | | 2014-03-15 11:17:28 | | 2014-03-15 10:00:11 | | 2014-03-15 07:45:27 | | 2014-03-15 07:forty two:19 | | 2014-03-14 09:38:12 |

    That doesn’t aid a noteworthy deal. Let’s eradicate the hours from the timestamp. That’s effortless:

    opt for distinct solid(login_time AS DATE) AS login_date FROM logins where user_id = :user_id

    Which yields:

    | LOGIN_DATE | |------------| | 2014-03-18 | | 2014-03-sixteen | | 2014-03-15 | | 2014-03-14 |

    Now, that we’ve discovered about window capabilities, let’s just add an light row number to every of those dates:

    select login_date, row_number() OVER (ORDER by route of login_date) FROM login_dates

    Which produces:

    | LOGIN_DATE | RN | |------------|----| | 2014-03-18 | four | | 2014-03-sixteen | 3 | | 2014-03-15 | 2 | | 2014-03-14 | 1 |

    nonetheless convenient. Now, what occurs, if instead of deciding on these values separately, they subtract them?

    opt for login_date - row_number() OVER (ORDER through login_date) FROM login_dates

    We’re getting some thing enjoy this:

    | LOGIN_DATE | RN | GRP | |------------|----|------------| | 2014-03-18 | four | 2014-03-14 | | 2014-03-sixteen | three | 2014-03-13 | | 2014-03-15 | 2 | 2014-03-13 | | 2014-03-14 | 1 | 2014-03-13 |

    Wow. entertaining. So, 14 – 1 = 13, 15 – 2 = 13, 16 – 3 = 13, however 18 – 4 = 14. no person can advise it greater than Doge:

    eder 3

    There’s a simple illustration for this behavior:

  • ROW_NUMBER() in no route has gaps. That’s how it’s described
  • Our records, youngsters, does
  • So when they subtract a “gapless” sequence of consecutive integers from a “gapful” sequence of non-consecutive dates, they are able to net the equal date for each “gapless” subseries of consecutive dates, and we’ll net a brand new date once more the situation the date collection had gaps.

    Huh.

    This means they can now without problems community via this capricious date value:

    choose min(login_date), max(login_date), max(login_date) - min(login_date) + 1 AS durationFROM login_date_groups community through grp ORDER via size DESC

    And we’re done. The biggest progression of consecutive dates with out a gaps has been discovered:

    5. discovering the size of a collection

    previously, they had considered progression of consecutive values. That’s convenient to assume keeping of as they can mistreat of the consecutiveness of integers. What if the definition of a “series” is less intuitive, and in addition to that, several sequence contain the same values? deem the following facts, the situation size is the size of each and every sequence that they are looking to calculate:

    | identification | VALUE_DATE | amount | size | |------|------------|--------|------------| | 9997 | 2014-03-18 | 99.17 | 2 | | 9981 | 2014-03-16 | 71.44 | 2 | | 9979 | 2014-03-16 | -94.60 | 3 | | 9977 | 2014-03-16 | -6.ninety six | 3 | | 9971 | 2014-03-15 | -65.ninety five | 3 | | 9964 | 2014-03-15 | 15.13 | 2 | | 9962 | 2014-03-15 | 17.forty seven | 2 | | 9960 | 2014-03-15 | -three.fifty five | 1 | | 9959 | 2014-03-14 | 32.00 | 1 |

    yes, you’ve guessed appropriate. A “series” is defined through the incontrovertible fact that consecutive (ordered through identification) rows possess the identical signal(quantity). assess once again the records formatted as under:

    | identification | VALUE_DATE | amount | size | |------|------------|--------|------------| | 9997 | 2014-03-18 | +99.17 | 2 | | 9981 | 2014-03-sixteen | +71.44 | 2 | | 9979 | 2014-03-16 | -ninety four.60 | 3 | | 9977 | 2014-03-16 | - 6.96 | three | | 9971 | 2014-03-15 | -65.ninety five | three | | 9964 | 2014-03-15 | +15.13 | 2 | | 9962 | 2014-03-15 | +17.47 | 2 | | 9960 | 2014-03-15 | - 3.fifty five | 1 | | 9959 | 2014-03-14 | +32.00 | 1 |

    How can they achieve it? “easy”😉 First, let’s achieve away with the entire noise, and add one more row quantity:

    select id, quantity, sign(amount) AS signal, row_number() OVER (ORDER by identification DESC) AS rn FROM trx

    this will give us:

    | id | amount | note | RN | |------|--------|------|----| | 9997 | ninety nine.17 | 1 | 1 | | 9981 | 71.forty four | 1 | 2 | | 9979 | -94.60 | -1 | 3 | | 9977 | -6.ninety six | -1 | four | | 9971 | -65.ninety five | -1 | 5 | | 9964 | 15.13 | 1 | 6 | | 9962 | 17.47 | 1 | 7 | | 9960 | -three.fifty five | -1 | eight | | 9959 | 32.00 | 1 | 9 |

    Now, the subsequent goal is to produce here desk:

    | identification | quantity | signal | RN | LO | hi | |------|--------|------|----|----|----| | 9997 | 99.17 | 1 | 1 | 1 | | | 9981 | seventy one.forty four | 1 | 2 | | 2 | | 9979 | -ninety four.60 | -1 | 3 | 3 | | | 9977 | -6.ninety six | -1 | 4 | | | | 9971 | -65.ninety five | -1 | 5 | | 5 | | 9964 | 15.13 | 1 | 6 | 6 | | | 9962 | 17.forty seven | 1 | 7 | | 7 | | 9960 | -three.55 | -1 | eight | eight | eight | | 9959 | 32.00 | 1 | 9 | 9 | 9 |

    in this table, they exigency to replica the row number value into “LO” on the “reduce” halt of a sequence, and into “hello” at the “upper” halt of a collection. For this we’ll live the use of the magical LEAD() and LAG(). LEAD() can entry the n-th next row from the present row, whereas LAG() can entry the n-th customary row from the latest row. for instance:

    opt for lag(v) OVER (ORDER with the aid of v), v, lead(v) OVER (ORDER via v) FROM ( VALUES (1), (2), (three), (four) ) t(v)

    The above question produces:

    eder 4

    That’s staggering! live aware, with window capabilities, that you can role rankings or aggregations on a subset of rows relative to the present row. in the case of LEAD() and LAG(), they comfortably entry a unique row relative to the latest row, given its offset. here is effectual in so many instances.

    carrying on with with their “LO” and “hi” example, they can without problems write:

    select trx.*, CASE WHEN lag(signal) OVER (ORDER through identity DESC) != note THEN rn conclusion AS lo, CASE WHEN lead(signal) OVER (ORDER with the aid of identification DESC) != signal THEN rn conclusion AS hi, FROM trx

    … wherein they evaluate the “previous” note (lag(signal)) with the “current” signal (signal). in the event that they’re distinctive, they save the row number in “LO”, because that’s the lessen positive of their collection.

    Then they evaluate the “next” signal (lead(sign)) with the “current” note (signal). in the event that they’re diverse, they save the row quantity in “hello”, because that’s the higher positive of their collection.

    ultimately, a bit handrum NULL handling to net every dinky thing appropriate, and we’re achieved:

    choose -- With NULL handling... trx.*, CASE WHEN coalesce(lag(sign) OVER (ORDER by identity DESC), 0) != signal THEN rn halt AS lo, CASE WHEN coalesce(lead(signal) OVER (ORDER by identity DESC), 0) != signal THEN rn halt AS hi, FROM trx

    subsequent step. They wish “LO” and “hello” to issue in utter rows, no longer just at the “lessen” and “higher” bounds of a collection. E.g. enjoy this:

    | id | amount | signal | RN | LO | hi | |------|--------|------|----|----|----| | 9997 | 99.17 | 1 | 1 | 1 | 2 | | 9981 | 71.forty four | 1 | 2 | 1 | 2 | | 9979 | -94.60 | -1 | 3 | three | 5 | | 9977 | -6.ninety six | -1 | four | three | 5 | | 9971 | -sixty five.95 | -1 | 5 | three | 5 | | 9964 | 15.13 | 1 | 6 | 6 | 7 | | 9962 | 17.47 | 1 | 7 | 6 | 7 | | 9960 | -3.55 | -1 | eight | eight | 8 | | 9959 | 32.00 | 1 | 9 | 9 | 9 |

    We’re using a role that is available at the least in Redshift, Sybase SQL anywhere, DB2, Oracle. We’re the use of the “IGNORE NULLS” clause that may moreover live passed to a few window capabilities:

    opt for trx.*, last_value (lo) IGNORE NULLS OVER ( ORDER via identification DESC ROWS BETWEEN UNBOUNDED preceding AND current ROW) AS lo, first_value(hi) IGNORE NULLS OVER ( ORDER by using identification DESC ROWS BETWEEN latest ROW AND UNBOUNDED FOLLOWING) AS hello FROM trx

    lots of key terms! however the essence is at utter times the identical. From any given “present” row, they eye at utter of the “previous values” (ROWS BETWEEN UNBOUNDED preceding AND latest ROW), however ignoring utter the nulls. From those outdated values, they assume the final price, and that’s their new “LO” price. In other phrases, they assume the “closest preceding” “LO” price.

    The same with “hi”. From any given “existing” row, they examine utter of the “subsequent values” (ROWS BETWEEN existing ROW AND UNBOUNDED FOLLOWING), but ignoring utter of the nulls. From the subsequent values, they assume the first price, and that’s their new “hello” cost. In different words, they assume the “closest following” “hi” price.

    explained in Powerpoint:

    eder 4

    Getting it a hundred% suitable, with a dinky handrum NULL fiddling:

    select -- With NULL managing... trx.*, coalesce(last_value (lo) IGNORE NULLS OVER ( ORDER by means of identity DESC ROWS BETWEEN UNBOUNDED preceding AND present ROW), rn) AS lo, coalesce(first_value(hello) IGNORE NULLS OVER ( ORDER by route of identification DESC ROWS BETWEEN existing ROW AND UNBOUNDED FOLLOWING), rn) AS hi FROM trx

    finally, we’re simply doing a trivial final step, preserving in intelligence off-via-1 blunders:

    select trx.*, 1 + hi - lo AS periodFROM trx

    And we’re done. here’s their result:

    | identity | amount | signal | RN | LO | hi | length| |------|--------|------|----|----|----|-------| | 9997 | 99.17 | 1 | 1 | 1 | 2 | 2 | | 9981 | 71.44 | 1 | 2 | 1 | 2 | 2 | | 9979 | -94.60 | -1 | three | 3 | 5 | 3 | | 9977 | -6.ninety six | -1 | four | 3 | 5 | 3 | | 9971 | -sixty five.ninety five | -1 | 5 | three | 5 | three | | 9964 | 15.13 | 1 | 6 | 6 | 7 | 2 | | 9962 | 17.forty seven | 1 | 7 | 6 | 7 | 2 | | 9960 | -3.fifty five | -1 | eight | 8 | eight | 1 | | 9959 | 32.00 | 1 | 9 | 9 | 9 | 1 |

    And the whole query here:

    WITH trx1(identity, volume, signal, rn) AS ( select identification, amount, signal(volume), row_number() OVER (ORDER through identification DESC) FROM trx ), trx2(id, volume, sign, rn, lo, hi) AS ( select trx1.*, CASE WHEN coalesce(lag(sign) OVER (ORDER with the aid of identification DESC), 0) != note THEN rn conclusion, CASE WHEN coalesce(lead(signal) OVER (ORDER with the aid of identity DESC), 0) != signal THEN rn end FROM trx1 ) select trx2.*, 1 - last_value (lo) IGNORE NULLS OVER (ORDER by id DESC ROWS BETWEEN UNBOUNDED previous AND existing ROW) + first_value(hi) IGNORE NULLS OVER (ORDER by means of id DESC ROWS BETWEEN latest ROW AND UNBOUNDED FOLLOWING) FROM trx2

    6. The subset sum problem with SQL

    here's my common!

    what is the subset sum issue? ascertain a fun explanation here:https://xkcd.com/287

    And a humdrum one perquisite here:https://en.wikipedia.org/wiki/Subset_sum_problem

    well-nigh, for each of these totals…

    | id | total | |----|-------| | 1 | 25150 | | 2 | 19800 | | 3 | 27511 |

    … they want to locate the “most beneficial” (i.e. the closest) sum possible, such as any combination of those items:

    | identity | merchandise | |------|-------| | 1 | 7120 | | 2 | 8150 | | 3 | 8255 | | 4 | 9051 | | 5 | 1220 | | 6 | 12515 | | 7 | 13555 | | eight | 5221 | | 9 | 812 | | 10 | 6562 |

    As you’re utter brief along with your mental mathemagic processing, you've got instantly calculated these to live the optimal sums:

    how to achieve it with SQL? easy. simply create a CTE that consists of the entire 2n *possible* sums after which find the closest one for every complete:

    -- utter the feasible 2N sums WITH sums(sum, max_id, calc) AS (...) -- ascertain the greatest sum per “total” select totals.complete, something_something(complete - sum) AS ideal, something_something(total - sum) AS calc FROM draw_the_rest_of_the_*bleep*_owl

    however don’t live concerned, the retort is – once more – not utter that challenging (although it doesn’t operate as a result of the nature of the algorithm):

    WITH sums(sum, id, calc) AS ( select item, identity, to_char(merchandise) FROM items UNION ALL opt for item + sum, objects.identification, calc || ' + ' || item FROM sums combine gadgets ON sums.identification &lt; items.identification ) select totals.identity, totals.total, min (sum) retain ( DENSE_RANK FIRST ORDER by abs(total - sum) ) AS most appropriate, min (calc) maintain ( DENSE_RANK FIRST ORDER with the aid of abs(total - sum) ) AS calc, FROM totals pass live section of sums neighborhood by route of totals.identity, totals.complete

    in this article, I gained’t clarify the particulars of this answer, since the illustration has been taken from a outdated article so that you can ascertain perquisite here:

    appreciate studying the particulars, but fabricate certain to reach back lower back here for the closing four tricks:

    7. Capping a working complete

    to this point, we’ve seen how to calculate an “average” working complete with SQL using window functions. That become effortless. Now, how about if they cap the operating complete such that it never goes under zero? virtually, they want to calculate this:

    | DATE | amount | total | |------------|--------|-------| | 2012-01-01 | 800 | 800 | | 2012-02-01 | 1900 | 2700 | | 2012-03-01 | 1750 | 4450 | | 2012-04-01 | -20000 | 0 | | 2012-05-01 | 900 | 900 | | 2012-06-01 | 3900 | 4800 | | 2012-07-01 | -2600 | 2200 | | 2012-08-01 | -2600 | 0 | | 2012-09-01 | 2100 | 2100 | | 2012-10-01 | -2400 | 0 | | 2012-eleven-01 | 1100 | 1100 | | 2012-12-01 | 1300 | 2400 |

    So, when that astronomical terrible quantity -20000 turned into subtracted, instead of exhibiting the precise complete of -15550, they without rigor screen 0. In other words (or facts units):

    | DATE | amount | complete | |------------|--------|-------| | 2012-01-01 | 800 | 800 | most useful(0, 800) | 2012-02-01 | 1900 | 2700 | top of the line(0, 2700) | 2012-03-01 | 1750 | 4450 | most fulfilling(0, 4450) | 2012-04-01 | -20000 | 0 | most reliable(0, -15550) | 2012-05-01 | 900 | 900 | most beneficial(0, 900) | 2012-06-01 | 3900 | 4800 | most efficient(0, 4800) | 2012-07-01 | -2600 | 2200 | most appropriate(0, 2200) | 2012-08-01 | -2600 | 0 | most beneficial(0, -400) | 2012-09-01 | 2100 | 2100 | most effective(0, 2100) | 2012-10-01 | -2400 | 0 | choicest(0, -300) | 2012-eleven-01 | 1100 | 1100 | most beneficial(0, 1100) | 2012-12-01 | 1300 | 2400 | ideal(0, 2400)

    How will they achieve it?

    eder 4

    exactly. With obscure, dealer-certain SQL. in this case, we’re using Oracle SQL

    eder 4

    How does it work? especially effortless!

    just add mannequin after any desk, and moreover you’re opening up a can of staggering SQL worms!

    opt for ... FROM some_table -- save this after any table model ...

    as soon as they save mannequin there, they will implement spreadsheet trustworthy judgment without slow in their SQL statements, simply as with Microsoft Excel.

    the following three clauses are probably the most effectual and widely used (i.e. 1-2 per 12 months by any individual on this planet):

    mannequin -- The spreadsheet dimensions DIMENSION via ... -- The spreadsheet cellphone type MEASURES ... -- The spreadsheet formulation suggestions ...

    The that means of each and every of those three extra clauses is premiere defined with slides once again.

    The DIMENSION by using clause specifies the scale of your spreadsheet. unlike in MS Excel, that you can possess any number of dimensions in Oracle:

    eder 4

    The MEASURES clause specifies the values that are available in each cell of your spreadsheet. in contrast to in MS Excel, that you could possess an entire tuple in every phone in Oracle, not only a unique cost.

    eder 4

    The rules clause specifies the formulas that result to every telephone in your spreadsheet. in contrast to in MS Excel, these rules / formulas are centralized at a unique region, as an alternative of being save inside of each telephone:

    eder 4

    This design makes mannequin a bit of harder to use than MS Excel, but tons extra potent, if you dare. The entire query will then live “trivially”:

    choose * FROM ( opt for date, amount, 0 AS total FROM quantities ) mannequin DIMENSION by using (row_number() OVER (ORDER via date) AS rn) MEASURES (date, quantity, complete) rules ( complete[any] = superior(0, coalesce(total[cv(rn) - 1], 0) + volume[cv(rn)]) )

    This entire element is so potent, it ships with its own white paper via Oracle, so instead of explaining issues extra perquisite here in this article, delight achieve study the mind-blowing white paper:

    8. Time sequence sample recognition

    if you’re into fraud detection or some other container that runs existent time analytics on great records sets, time progression pattern awareness is not at utter a brand new term to you.

    If they assessment the “size of a collection” records set, they could wish to generate triggers on advanced pursuits over their time progression as such:

    | identity | VALUE_DATE | volume | LEN | set off |------|------------|---------|-----|-------- | 9997 | 2014-03-18 | + 99.17 | 1 | | 9981 | 2014-03-sixteen | - 71.forty four | four | | 9979 | 2014-03-16 | - 94.60 | 4 | x | 9977 | 2014-03-sixteen | - 6.ninety six | four | | 9971 | 2014-03-15 | - 65.ninety five | four | | 9964 | 2014-03-15 | + 15.13 | three | | 9962 | 2014-03-15 | + 17.forty seven | three | | 9960 | 2014-03-15 | + 3.fifty five | three | | 9959 | 2014-03-14 | - 32.00 | 1 |

    the guideline of the above set off is:

    trigger on the 3rd repetition of an event if the sustain occurs extra than 3 times.

    comparable to the customary model clause, they can achieve this with an Oracle-certain clause that turned into added to Oracle 12c:

    opt for ... FROM some_table -- save this after any desk to pattern-suit -- the desk’s contents MATCH_RECOGNIZE (...)

    The least difficult feasible software of MATCH_RECOGNIZE includes perquisite here subclauses:

    opt for * FROM seriesMATCH_RECOGNIZE ( -- pattern matching is executed in this order ORDER by means of ... -- These are the columns produced by route of matches MEASURES ... -- a brief specification of what rows are -- lower back from each in shape utter ROWS PER fit -- «ordinary expressions» of hobbies to healthy sample (...) -- The definitions of «what's an adventure» define ... )

    That sounds crazy. Let’s examine some instance clause implementations

    select * FROM collectionMATCH_RECOGNIZE ( ORDER by route of identification MEASURES classifier() AS trg utter ROWS PER suit sample (S (R X R+)?) outline R AS signal(R.volume) = prev(sign(R.volume)), X AS signal(X.quantity) = prev(signal(X.volume)) )

    What will they achieve perquisite here?

  • We order the desk by means of id, which is the order wherein they want to fit pursuits. convenient.
  • We then specify the values that they exigency in consequence. They wish the “MEASURE” trg, which is described because the classifier, i.e. the literal that we’ll use within the pattern afterwards. Plus they exigency utter of the rows from a match.
  • We then specify an everyday expression-like sample. The pattern is an adventure “S” for delivery, followed optionally by using “R” for Repeat, “X” for their particular event X, followed with the aid of one or more “R” for restate once again. If the complete pattern fits, they net SRXR or SRXRR or SRXRRR, i.e. X might live on the third situation of a sequence of length >= 4
  • ultimately, they outline R and X as being the same issue: The event whenSIGN(quantity) of the latest row is a similar as signal(quantity) of the outdated row. They don’t should outline “S”. “S” is simply another row.
  • This question will magically produce here output:

    | identity | VALUE_DATE | volume | TRG | |------|------------|---------|-----| | 9997 | 2014-03-18 | + ninety nine.17 | S | | 9981 | 2014-03-sixteen | - 71.forty four | R | | 9979 | 2014-03-16 | - ninety four.60 | X | | 9977 | 2014-03-sixteen | - 6.96 | R | | 9971 | 2014-03-15 | - sixty five.95 | S | | 9964 | 2014-03-15 | + 15.13 | S | | 9962 | 2014-03-15 | + 17.47 | S | | 9960 | 2014-03-15 | + three.55 | S | | 9959 | 2014-03-14 | - 32.00 | S |

    we can behold a unique “X” in their event circulation. exactly where they had expected it. on the third repetition of an sustain (identical signal) in a sequence of size > 3.

    increase!

    As they don’t truly keeping about “S” and “R” pursuits, let’s just net rid of them as such:

    opt for id, value_date, volume, CASE trg WHEN 'X' THEN 'X' halt trg FROM seriesMATCH_RECOGNIZE ( ORDER through identity MEASURES classifier() AS trg utter ROWS PER suit pattern (S (R X R+)?) define R AS signal(R.volume) = prev(sign(R.amount)), X AS sign(X.amount) = prev(sign(X.volume)) )

    to supply:

    | id | VALUE_DATE | amount | TRG | |------|------------|---------|-----| | 9997 | 2014-03-18 | + ninety nine.17 | | | 9981 | 2014-03-sixteen | - 71.44 | | | 9979 | 2014-03-sixteen | - ninety four.60 | X | | 9977 | 2014-03-sixteen | - 6.ninety six | | | 9971 | 2014-03-15 | - 65.95 | | | 9964 | 2014-03-15 | + 15.13 | | | 9962 | 2014-03-15 | + 17.forty seven | | | 9960 | 2014-03-15 | + 3.fifty five | | | 9959 | 2014-03-14 | - 32.00 | |

    thanks Oracle!

    9. Pivoting and Unpivoting

    in case you’ve examine this a long way, the following will live almost too embarassingly fundamental:

    | title | TITLE | score | |-----------|-----------------|--------| | A. provide | ANNIE id | G | | A. provide | DISCIPLE mom | PG | | A. outfit | GLORY TRACY | PG-13 | | A. HUDSON | LEGEND JEDI | PG | | A. CRONYN | IRON MOON | PG | | A. CRONYN | girl STAGE | PG | | B. WALKEN | SIEGE MADRE | R |

    here is what they title pivoting:

CRONYN | 6 | 9 | 2 | 6 | four | | B. WALKEN | eight | eight | four | 7 | three | | B. WILLIS | 5 | 5 | 14 | 3 | 6 | | C. DENCH | 6 | 4 | 5 | 4 | 5 | | C. NEESON | three | 8 | 4 | 7 | three |

    look at how they kinda grouped by route of the actors after which “pivoted” the quantity films per rating each and every actor performed in. in its situation of exhibiting this in a “relational” manner, (i.e. each and every neighborhood is a row) they pivoted the whole factor to produce a column per group. they are able to try this, as a result of they understand utter the viable groups in improve.

    Unpivoting is the opposite, when from the above, they exigency to net lower back to the “row per community” representation:

    | identify | score | signify number | |-----------|--------|-------| | A. provide | NC-17 | 3 | | A. supply | PG | 6 | | A. provide | G | 5 | | A. provide | PG-13 | three | | A. award | R | 6 | | A. HUDSON | NC-17 | 12 | | A. HUDSON | PG | 4 |

    It’s definitely in reality effortless. here's how we’d achieve it in PostgreSQL:

    choose first_name, last_name, signify number(*) FILTER (the situation score = 'NC-17') AS "NC-17", count(*) FILTER (where ranking = 'PG' ) AS "PG", signify number(*) FILTER (the situation rating = 'G' ) AS "G", signify number(*) FILTER (where rating = 'PG-13') AS "PG-13", count(*) FILTER (where score = 'R' ) AS "R" FROM actor AS a be section of film_actor AS fa using (actor_id) join movie AS f the usage of (film_id) neighborhood by actor_id

    we can append an light FILTER clause to an combination feature as a route to signify number only probably the most statistics.

    In utter other databases, we’d achieve it enjoy this:

    opt for first_name, last_name, signify number(CASE rating WHEN 'NC-17' THEN 1 end) AS "NC-17", signify number(CASE score WHEN 'PG' THEN 1 conclusion) AS "PG", count(CASE score WHEN 'G' THEN 1 end) AS "G", signify number(CASE ranking WHEN 'PG-13' THEN 1 conclusion) AS "PG-13", count(CASE score WHEN 'R' THEN 1 end) AS "R" FROM actor AS a join film_actor AS fa the usage of (actor_id) be section of movie AS f the use of (film_id) community through actor_id

    The fine issue here is that combination services usually simplest accept as exact with non-NULL values, so if they fabricate the entire values NULL that aren't pleasing per aggregation, we’ll net the same effect.

    Now, in case you’re the usage of either SQL Server, or Oracle, that you would live able to use the constructed-in PIVOT or UNPIVOT clauses as a substitute. once again, as with mannequin or MATCH_RECOGNIZE, simply append this new keyword after a desk and net the equal effect:

    -- PIVOTING select whatever, some thing FROM some_table PIVOT ( signify number(*) FOR rating IN ( 'NC-17' AS "NC-17", 'PG' AS "PG", 'G' AS "G", 'PG-13' AS "PG-13", 'R' AS "R" ) ) -- UNPIVOTING opt for whatever thing, anything FROM some_table UNPIVOT ( signify FOR score IN ( "NC-17" AS 'NC-17', "PG" AS 'PG', "G" AS 'G', "PG-13" AS 'PG-13', "R" AS 'R' ) )

    handy. next.

    10. Abusing XML and JSON

    First off

    eder 4

    JSON is simply XML with less facets and fewer syntax

    Now, everybody knows that XML is incredible. The corollary is for that reason:

    JSON is much less superb

    Don’t use JSON.

    Now that we’ve settled this, they can safely ignore the ongoing JSON-in-the-database-hype (which most of you are going to heartache in five years anyway), and rush on to the final instance. the route to achieve XML within the database.

    here is what they wish to do:

    eder 4

    Given the customary XML document, they are looking to parse that document, unnest the comma-separated list of movies per actor, and produce a denormalized representation of actors/movies in a unique relation.

    in a position. Set. Go. here's the idea. they possess three CTE:

    WITH RECURSIVE x(v) AS (choose '...'::xml), actors( actor_id, first_name, last_name, films ) AS (...), movies( actor_id, first_name, last_name, film_id, movie ) AS (...) choose * FROM movies

    within the first one, they conveniently parse the XML. perquisite here with PostgreSQL:

    WITH RECURSIVE x(v) AS (opt for ' Bud Spencer God Forgives... I Don’t, Double predicament, They title Him Bulldozer Terence Hill God Forgives... I Don’t, Double problem, fortunate Luke '::xml), actors(actor_id, first_name, last_name, films) AS (...), films(actor_id, first_name, last_name, film_id, film) AS (...) opt for * FROM movies

    effortless.

    Then, they achieve some XPath magic to extract the particular person values from the XML constitution and save these into columns:

    WITH RECURSIVE x(v) AS (select '...'::xml), actors(actor_id, first_name, last_name, films) AS ( opt for row_number() OVER (), (xpath('//first-identify/textual content()', t.v))[1]::textual content, (xpath('//closing-name/textual content()' , t.v))[1]::text, (xpath('//movies/textual content()' , t.v))[1]::text FROM unnest(xpath('//actor', (opt for v FROM x))) t(v) ), movies(actor_id, first_name, last_name, film_id, film) AS (...) choose * FROM films

    nonetheless easy.

    at last, just more or less of recursive accustomed expression pattern matching magic, and we’re executed!

    WITH RECURSIVE x(v) AS (select '...'::xml), actors(actor_id, first_name, last_name, films) AS (...), films(actor_id, first_name, last_name, film_id, film) AS ( opt for actor_id, first_name, last_name, 1, regexp_replace(movies, ',.+', '') FROM actors UNION ALL opt for actor_id, a.first_name, a.last_name, f.film_id + 1, regexp_replace(a.movies, '.*' || f.film || ', ?(.*?)(,.+)?', '\1') FROM movies AS f combine actors AS a using (actor_id) the situation a.films now not enjoy '%' || f.film ) select * FROM movies

    Let’s conclude:

    eder 4

    Conclusion

    All of what this article has proven became declarative. and relatively effortless. Of route, for the enjoyable result that I’m trying to obtain during this talk, some exaggerated SQL become taken and i expressly called everything “easy”. It’s no longer at utter easy, you should rehearse SQL. enjoy many other languages, however more or less harder as a result of:

  • The syntax is a dinky gauche every now and then
  • Declarative pondering is not easy. at least, it’s very distinctive
  • however once you net a cling of it, declarative programming with SQL is completely worth it as that you may specific complicated relationships between your statistics in very very dinky code with the aid of simply describing the result you are looking to net from the database.

    Isn’t that mind-blowing?

    And if that changed into a dinky over the top, achieve note that I’m satisfied to hunt counsel from your JUG / convention to give this talk (simply contact us), or if you are looking to net in reality down into the details of those things, they moreover present this speak as a public or in-condominium workshop. achieve net in touch! We’re searching forward.

    Introducing Force.com | killexams.com existent questions and Pass4sure dumps

    This chapter introduces the concepts, terminology, and technology components of the Force.com platform and its context in the broader Platform as a Service (PaaS) landscape. The goal is to provide context for exploring Force.com within a corporate software evolution organization.

    This chapter is from the book 

    If any of the following sentences depict you, this chapter is intended to help:

  • You possess read about cloud computing or PaaS and want to learn how Force.com compares to other technologies.
  • You want to net started with Force.com but exigency to select a suitable first project.
  • You possess a project in intelligence to build on Force.com and want to learn how you can leverage existing evolution skills and process.
  • This chapter consists of three sections:

  • Force.com in the Cloud Computing Landscape: Learn about PaaS and Force.com's unique features as a PaaS solution.
  • Inside a Force.com Project: Examine how application evolution with Force.com differs from other technologies in terms of project selection, technical roles, and tools.
  • Sample Application: A sample business application is referenced throughout this book to provide a concrete basis for discussing technical problems and their solutions. In this chapter, the sample application's requirements and use cases are outlined, as well as a evolution plan, mapped to chapters of the book.
  • Phrases enjoy "cloud computing" and "Platform as a Service" possess many meanings save forth by many vendors. This section provides definitions of the terms to serve as a basis for understanding Force.com and comparing it with other products in the market. With this background, you can fabricate the best preference for your projects, whether that is Force.com, another PaaS product, or your own in-house infrastructure.

    Platform as a Service (PaaS)

    The platform is infrastructure for the evolution of software applications. The functionality of a platform's infrastructure differs widely across platform vendors, so this section focuses on a handful of the most established vendors. The suffix "as a Service" (aaS) means that the platform exists "in the cloud," accessible to customers via the Internet. Many variations exist on this acronym, including SaaS (Software as a Service), IaaS (Infrastructure as a Service), and so forth.

    PaaS is a category within the umbrella of cloud computing. "Cloud computing" is a phrase to depict the movement of computing resources away from physical data centers or servers in a closet in your company and into the network, where they can live provisioned, accessed, and deprovisioned instantly. You plug a lamp into an electrical socket to use the electrons in your region's power grid. Running a diesel generator in your basement is usually not necessary. You faith that the power company is going to provide that service, and you pay the company as you use the service.

    Cloud computing as a general concept spans every conceivable configuration of infrastructure, well outside the scope of this book. The potential benefits are reduced complexity and cost versus a traditional approach. The traditional approach is to invest in infrastructure by acquiring new infrastructure assets and staff or redeploying or optimizing existing investments. Cloud computing provides an alternative.

    Many companies provide PaaS products. The following subsections interpolate the mainstream PaaS products and comprise brief descriptions of their functionality. Consult the Web sites of each product for further information.

    Amazon Web Services

    Amazon Web Services refers to a family of cloud computing products. The most apposite to PaaS is Elastic Beanstalk, a platform for running Java applications that provides load balancing, auto-scaling, and health monitoring. The platform is actually built on several other Amazon Web Services products that can live independently configured by advanced users, with the most significant being Elastic Compute Cloud (EC2). EC2 is a general-purpose computing platform, not limited to running Java programs. You can provision virtual instances of Windows or Linux machines at will, loading them with your own custom operating-system image or one prebuilt by Amazon or the community. These instances Run until you shut them down, and you are billed for usage of resources such as CPU, disk, and network.

    A raw machine with an OS on it is a noteworthy start, but to build a business application requires you to install, manage access to, maintain, monitor, patch and upgrade, back up, blueprint to scale, and generally keeping and feed in perpetuity an application platform on the EC2 instance. Many of these tasks are soundless required of Amazon's higher-level Elastic Beanstalk offering. If your organization has the skills to build on .NET, J2EE, LAMP, or other application stacks, plus the OS, database administration, and IT operations experience, Amazon's virtual servers in the cloud could live a tenacious alternative to running your own servers in-house.

    Amazon provides various other products that complement Elastic Beanstalk and EC2. These comprise Simple Queue Service for publish-and-subscribe-style integration between applications, Simple DB for managing schemaless data, and Simple Storage Service, a content repository.

    Microsoft Azure

    Azure consists of two products. The first is Windows Azure, an operating system that can utilize Microsoft's data centers for general computation and storage. It is a combination of infrastructure and platform designed to assume existing and new .NET-based applications and Run them in the cloud, providing similar features for scalability and elasticity as Amazon Web Services. Most Azure applications are developed in C# using Microsoft Visual Studio, although other languages and tools are supported. The second section is SQL Azure, a hosted version of Microsoft SQL Server. The cost of these products is based on resource consumption, defined as a combination of CPU, network bandwidth, storage, and number of transactions.

    Google App Engine

    App Engine is a platform designed for hosting Web applications. App Engine is enjoy having an unlimited number of servers in the cloud working for you, preconfigured with a distributed data store and Python or Java-based application server. It's much enjoy Amazon's Elastic Beanstalk but focused on providing a higher-level application platform. It lacks the configurable lower-level services enjoy EC2 to provide an shun hatch for developers requiring more control over the infrastructure. App Engine includes tools for managing the data store, monitoring your site and its resource consumption, and debugging and logging.

    App Engine is free for a set amount of storage and page views per month. Applications requiring more storage or bandwidth can purchase it by setting a maximum daily dollar amount they're willing to spend, divided into five buckets: CPU time, bandwidth in, bandwidth out, storage, and outbound email.

    Force.com

    Force.com is targeted toward corporate application developers and independent software vendors. Unlike the other PaaS offerings, it does not expose developers directly to its own infrastructure. Developers achieve not provision CPU time, disk, or instances of running operating systems. Instead, Force.com provides a custom application platform centered around the relational database, one resembling an application server stack you might live confidential with from working with .NET, J2EE, or LAMP.

    Although it integrates with other technologies using open standards such as SOAP and REST, the programming languages and metadata representations used to build applications are proprietary to Force.com. This is unique among the PaaS products but not unreasonable when examined in depth. Force.com operates at a significantly higher plane of abstraction than the other PaaS products, promising dramatically higher productivity to developers in recrudesce for their investment and faith in a single-vendor solution.

    To extend the reach of Force.com to a larger developer community, Salesforce and VMware provide a product called VMforce. VMforce brings some of the features of the Force.com platform to Java developers. It consists of evolution tools from the Salesforce community and virtualized computing resources from VMware. With VMforce, you can create hybrid applications that use Force.com for data and services, but are built with Java benchmark technologies such as Spring. Along the same lines, Salesforce's acquisition of Heroku is expected to extend Force.com features to Ruby developers.

    Force.com is free for developers. Production applications are priced primarily by storage used and number of unique users.

    Facebook

    Facebook is a Web site for connecting with your friends, but it moreover provides developers with ways to build their own socially alert applications. These applications leverage the Facebook service to create new ways for users to interact while online. The Facebook platform is moreover accessible to applications not built inside Facebook, exposing the "social graph" (the network of relationships between users) where permitted.

    Much of the value of Facebook as a platform stems from its great user base and consistent yet extensible user experience. It is a set of services for adding gregarious context to applications. Unlike Force.com and App Engine, for example, Facebook has no facility to host custom applications.

    Force.com as a Platform

    Force.com is different from other PaaS solutions in its focus on business applications. Force.com is a section of Salesforce.com, which started as a SaaS Customer Relationship Management (CRM) vendor. But Force.com is not CRM. It provides the infrastructure commonly needed for any business application, customizable for the unique requirements of each business through a combination of code and configuration. This infrastructure is delivered to you as a service on the Internet.

    Because you are reading this book, you possess probably developed a few business applications in your time. deem the features you implemented and reimplemented in multiple applications, the unglamorous plumbing, wiring, and foundation work. Some examples are security, user identity, logging, profiling, integration, data storage, transactions, workflow, collaboration, and reporting. This infrastructure is essential to your applications but expensive to develop and maintain. business application developers achieve not code their own relational database kernels, windowing systems, or operating systems. This is basic infrastructure, acquired from software vendors or the open-source community and then configured to meet user requirements. What if you could achieve the same for your application infrastructure? This is the premise of the Force.com.

    The following subsections list differentiating architectural features of Force.com with brief descriptions.

    Multitenancy

    Multitenancy is an abstract concept, an implementation detail of Force.com, but one with tangible benefits for developers. motif 1-1 shows a conceptual view of multitenancy. Customers access shared infrastructure, with metadata and data stored in the same analytic database.

    The multitenant architecture of Force.com consists of the following features:

  • Shared infrastructure: Every customer (or tenant) of Force.com shares the same infrastructure. They are assigned an independent analytic environment within the Force.com platform.

    At first, some might live uncomfortable with the thought of handing their data to a third-party where it is co-mingled with that of competitors. Salesforce's whitepaper on its multitenant technology includes the technical details of how it works and why your data is safe from loss or impulsive appearance to unauthorized parties.

  • Single version: Only one version of the Force.com platform is in production. The same platform is used to deliver applications of utter sizes and shapes, used by 1 to 100,000 users, running everything from dog-grooming businesses to the Japanese national post office.
  • Continuous, zero-cost improvements: When Force.com is upgraded to comprise new features or bug fixes, the upgrade is enabled in every customer's analytic environment with zero to minimal exertion required.
  • Salesforce can roll out new releases with self-possession because it maintains a unique version of its infrastructure and can achieve broad test coverage by leveraging tests, code, and configurations from their production environment. You, the customer, are helping maintain and help Force.com in a systematic, measurable route as a side result of simply using it. This profound feedback loop between the Force.com and its users is something impractical to achieve with on-premise software.

    Relational Database

    The heart of Force.com is the relational database provided as a service. The relational database is the most well-understood and widely used route to store and manage business data. business applications typically require reporting, transactional integrity, summarization, and structured search, and implementing those on nonrelational data stores requires significant effort. Force.com provides a relational database to each tenant, one that is tightly integrated with every other feature of the platform. There are no Oracle licenses to purchase, no tablespaces to configure, no JDBC drivers to install, no ORM to wrangle, no DDL to write, no queries to optimize, and no replication and backup strategies to implement. Force.com takes keeping of utter these tasks.

    Application Services

    Force.com provides many of the common services needed for modern business application development. These are the services you might possess built or integrated repeatedly in your past evolution projects. They comprise logging, transaction processing, validation, workflow, email, integration, testing, reporting, and user interface.

    These services are highly customizable with and without writing code. Although each service can live valued as an individual unit of functionality, their unification offers tremendous value. utter the features of Force.com are designed, built, and maintained by a unique responsible party, Salesforce. Salesforce provides documentation for these features as well as uphold staff on-call, training and certification classes, and accountability to its customers for keeping things running smoothly. This is in contrast to many software projects that halt up as a patchwork of open-source, best-of-breed tools and libraries glued together by you, the developer, asked to achieve more with fewer people, shorter timelines, and cheaper, often unsupported tools.

    Declarative Metadata

    Almost every customization configured or coded within Force.com is readily available as simple XML with a documented schema. At any point in time, you can inquire Force.com for this metadata via a set of Web services. The metadata can live used to configure an identical environment or managed with your corporate benchmark source control system. It is moreover helpful for troubleshooting, allowing you to visually compare the status of two environments. Although a few features of Force.com are not available in this declarative metadata form, Salesforce's stated product direction is to provide full coverage.

    Programming Language

    Force.com has its own programming language, called Apex. It allows developers to script interactions with other platform features, including the user interface. Its syntax is a blend of Java and database stored procedure languages enjoy T/SQL and can live written using a Web browser or a plug-in to the Eclipse IDE.

    Other platforms assume a different approach. Google's App Engine simultaneously restricts and extends existing languages such as Python so that they play nicely in a PaaS sandbox. This offers obvious benefits, such as leveraging the evolution community, ease of migration, and skills preservation. One route to understand Apex is as a domain-specific language. Force.com is not a general-purpose computing platform to Run any Java or C# program you want to run. Apex is kept intentionally minimalistic, designed with only the needs of Force.com developers in mind, built within the controlled environment of Salesforce R&D. Although it won't unravel every programming problem, Apex's specialized nature leads to some advantages in learning curve, code conciseness, ease of refactoring, and ongoing maintenance costs.

    Force.com Services

    Force.com can live divided into four major services: database, business logic, user interface, and integration. Technically, many more services are provided by Force.com, but these are the high-level categories that are most apposite to new Force.com developers.

    Database

    Force.com is built around a relational database. It allows the definition of custom tables containing up to 800 fields each. Fields contain strongly typed data using any of the benchmark relational database data types, plus rich types such as currency values, picklists, formatted text, and phone numbers. Fields can contain validation rules to ensure data is clean before being committed, and formulas to derive values, enjoy cells in a spreadsheet. realm history tracking provides an audit log of changes to chosen fields.

    Custom tables can live related to each other, allowing the definition of involved data schemas. Tables, rows, and columns can live configured with security constraints. Data and metadata is protected against accidental deletion through a "recycling bin" metaphor. The database schema is often modifiable instantly, without manual migration. Data is imported from files or other sources with free tools, and APIs are provided for custom data-loading solutions.

    Data is queried via a SQL-like language called SOQL (Salesforce protest Query Language). Full-text search is available through SOSL (Salesforce protest Search Language).

    Business Logic

    Apex is the language used to implement business logic on Force.com. It allows code to live structured into classes and interfaces, and it supports object-oriented behaviors. It has strongly typed collection objects and arrays modeled after Java.

    Data binding is a first-class concept in Apex, with the database schema automatically imported as language constructs. Data manipulation statements, trigger semantics, batch processing, and transaction boundaries are moreover section of the language.

    The philosophy of test-driven evolution is hard-wired into the Force.com platform. Methods are annotated as tests and Run from a provided test harness or test API calls. Test methods are automatically instrumented by Force.com and output timing information for performance tuning. Force.com prevents code from being deployed into production that does not possess adequate unit test coverage.

    User Interface

    Force.com provides two approaches for the evolution of user interfaces: Page Layouts and Visualforce. Page Layouts are inferred from the data model, including validation rules, and then customized using a WYSIWYG editor. Page Layouts feature the benchmark Salesforce look-and-feel. For many applications, Page Layouts can deliver some or utter of the user interface with no evolution effort.

    Visualforce allows developers to build custom user interfaces. It consists of a progression of XML markup tags called components with their own namespace. As with JSP, ASP.NET, Velocity, and other template processing technologies, the components serve as containers to structure data returned by the Controller, a class written in Apex. To the user, the resulting Web pages might eye nothing enjoy Salesforce, or adopt its benchmark look-and-feel. Visualforce components can express the many types and styles of UIs, including basic entry forms, lists, multistep wizards, Ajax, Adobe Flex, mobile applications, and content management systems. Developers can create their own components to reuse across applications.

    User interfaces in Visualforce are public, private, or some blend of the two. Private user interfaces require a user to log in before gaining access. Public user interfaces, called Sites, can live made available to anonymous users on the Internet.

    Integration

    In the world of integration, more options are usually better, and standards uphold is essential. Force.com supports a wide array of integration technologies, almost utter of them based on industry-standard protocols and message formats. You can integrate other technologies with Force.com using an approach of configuration plus code. Here are some examples:

  • Apex Web Services allows control of data, metadata, and process from any platform supporting SOAP over HTTP, including JavaScript. This makes writing composite applications that combine Force.com with technology from other vendors in many affecting and powerful ways possible. Force.com's Web services API has evolved over many years, spanning more than 20 versions with full backward compatibility.
  • The Force.com database is accessible via Representational status Transfer (REST) calls. This integration fashion is much lighter weight than Web Services, allowing Web applications to query and modify data in Force.com with simple calls accessible to any evolution language.
  • Business logic developed in Apex can live exposed as a Web service, accessible with or without a Force.com user identity. Force.com generates the WSDL from your Apex code. Additionally, Force.com converts WSDL to Apex bindings to allow access to external Web services from within the platform.
  • You can create virtual email inboxes on Force.com and write code to process the incoming email. Sending email from Force.com is moreover supported.
  • Force.com provides an API for making HTTP requests, including uphold for client-side certificates, SSL, proxies, and HTTP authentication. With this, you can integrate with Web-based resources, everything from static Web pages to repose services returning JSON.
  • Salesforce-to-Salesforce (S2S) is a publish-and-subscribe model of data sharing between multiple Force.com environments. If the company you exigency to integrate with already uses Force.com and the data is supported by S2S, integration becomes a relatively simple configuration exercise. There is no code or message formats to maintain. Your data is transported within the Force.com environment from one tenant to another.
  • If your requirements ordain a higher-level approach to integration, software vendors enjoy IBM's Cast Iron Systems and Informatica present adapters to Force.com to read and write data and orchestrate involved transactions spanning disparate systems.
