Instead of just focusing on the major features of IBM Cognos 10 Report Studio, Roger Johnson, coauthor of IBM Cognos 10 Report Studio: Practical Examples, looks at some lesser-known tools and expostulate properties to further enhance your Report Studio projects.
From the author of
The biggest additions to IBM Cognos Report Studio in version 10 abide been energetic Reports and Statistics objects. These two original ways of presenting data provide many original options for report authors to create reports that match the analytical needs of the user community. Entire classes abide been created to focus on the creation of reports using these formats.
Other capabilities in IBM Cognos 10 Report Studio comprehend the integration of external data sources and the ability to reclaim Report Studio reports to subsist used directly by business Insight Advanced authors. Using external data sources in Report Studio has been a customer request since IBM Cognos tools moved to a web-based architecture. This enhancement gives the report consumer original opportunities to process just the information needed for a specific situation. By using a common report definition between applications, users who aren't accustomed to tangled reports can receive assistance to build reports that abide features beyond those normally available to business Insight Advanced users.
While the features I've discussed to this point are promoted as key features, other useful options in version 10 will multiply the effectiveness of reports to your users. Some of these features were previously available through tangled programming by the report developer, but IBM Cognos business Intelligence now makes this job much easier. As a report writer and instructor who can prize the ability to create report designs designed to declare a story, I want to highlight 10 of these original features.
The Alternative Text property has been added to graphical objects, such as images and charts, to allow screen readers to translate the text (see pattern 1). Another aspect of this feature that's applied in various properties is to provide localized text without using conditional formatting.
Colored Regions, Plot area Fill, Material Effects
The Colored Regions, Plot area Fill, and Material Effects properties allow charts to abide more creative designs in order to enhance the overall presentation of the charts. Mixed with other chart presentation options, these features serve report developers to give original polish to the presentation of content. pattern 2 shows the additional gradient options that are now available, along with the original properties for the charts.
New Gradient Fill Types
Moving beyond simple linear gradients, some original fill types provide more choices for enhanced presentations. Backgrounds behind pages, objects, and selected areas can now panoply a number of gradient designs. The fill types comprehend rectangular frames and embedded circular gradients, with many parameters to customize the blending of colors (see pattern 3).
Chart Combinations (Primary Axis, Secondary Axis, Primary Bottom, Secondary Bottom)
IBM Cognos 8 business Insight had the ability to set Y1 and Y2 axes. Now combination charts can subsist stacked with two more axes for better analysis of related numbers. These options can subsist integrated into dashboard design to enhance the presentation of related measures. pattern 4 shows a chart with the additional axes selected.
Query Calculations in Query Explorer supplant Calculated Member, Calculated Measure, Set Expression, and Intersection (tuple)
In IBM Cognos 8 Report Studio, different objects were created for each of the dimensional functions. Now they're sum bundled into the Query Calculations (see pattern 5). This option simplifies the toolbox for report authors, while emphasizing that dimensional queries can abide enhanced calculations.
Summarize petite Slices and Exploded Slices
With pie charts, two improvements comprehend summarizing petite slices and exploding slices. These two options greatly help the presentation of pie charts to emphasize the most notable information (see pattern 6). In my classes, these options abide been requested for years, and now they're delivered in this release.
Trendlines, Category Baselines, and Numeric Baselines
Report Studio functions abide now improved on the predictive ability behind charts, without having to utilize external functions to pattern the numbers (see pattern 7).
Series Color Synchronization
With the changes made to enhance series, this feature allows report writers to simplify the legends when the chain information is repeated across the combinations. By changing the chain Color property to Match (see the short arrow in pattern 8), the legend shows the different product lines and the nested measures differently (indicated by the longer arrow), increasing the effectiveness of the presentation.
Custom Properties for Prompts
Dimensional Set Definitions
As a welcome addition to dimensional functions, the Set Definition option (see pattern 10) allows report authors to create tangled subsets that are presented graphically. This feature can design troubleshooting tangled sets much easier by providing a more modular approach to set development. This was the best original property for me, since it simplifies the progress of sets that had to subsist plenary of nested functions.

These days there are so many companies trying to build data warehouses and there are a lot of companies selling business intelligence products. The original version of SQL Server 2005 has the business Intelligence progress Studio and this is one of its main upgrade from SQL Server 2000. It enhanced the DTS environment and changed its designation to Integration Services (SSIS), which is similar to an ETL tool. It integrated with .NET so it can easily build reports or online applications. Microsoft is definitely putting its energy in the data warehouse business.
Also SQL Server is gaining on the market participate of other RDBMSs and most experts said it was because of the BI integration. However, does your company requisite a data warehouse? And how enact you elect the right BI product for your company?
First it must subsist the business direction that produces the driving coerce to build the data warehouse and not the IT department. The company must identify the goals and objectives of 'why install a data warehouse'.
For example, my customary company was a bank; it decided to build a data warehouse so it could maintain track of a loan from the application process until repayment. One objective was the business wanted to find out how long it took the loan from application status to approval status, and if the loan got denied, they wanted to find out what the intuition was. However when the company decided to build the data warehouse, the IT department helped the organization to understand the scope of the project. The business has to identify what the enterprise needs. It has to rule how much they want to spend on the project, what benign of data they want to capture, etc. This helps to determine what benign of hardware, operating system, communication links, RDBMS and application program IT needs. The business moreover has to understand that it is a continuous project, both business and IT has to rule who is accountable to fix problem, who is accountable for original requests and who is accountable for tuning. It needs continuous champion from the business.
The IT department has to know what they requisite in order to build a successful data warehouse. First they requisite to understand the business data. It needs an implementation plan, a realistic timeline, a team of people with knowledge to build the data warehouse - a data architect, a data modeler, business analyst, data character administrator, meta data administrator, security administrator and splendid database developers. The scope of the project has to subsist reasonable; sometimes the business tends to quiz too much at once, the IT manager has to understand one thing - never takes on too much too fast. It tends to fail.
Data is an notable asset to the business; it helps the business to design daily determination and direction of the organization. Data character is the most notable element of the data warehouse. Data character and integrity can directly influence many decisions. The data warehouse is not just capturing data. It can moreover minimize data redundancy, multiply customer satisfaction, help data quality, and provide splendid customer reports. So the business needs to set up a metrics to measure if the data warehouse is successful. The response time, the character of the data, the satisfaction of the customers are some of the measurements the business needs to recognize at. If the data is incorrect and no one trusts the data warehouse, it becomes a total bunch of tables sitting in a database.
In a lot of companies, the data can near from ERP systems, legacy systems, outside sources and even may subsist surpass sheets on someone's PC. The data warehouse team has to seize responsibility to validate the data, to drudgery with the business to set up business rules and to drudgery with data owner to set up security for the data. This is Part of the ETL process.
For example, the ERP system had a customer designation 'John Doe'; the legacy system had a customer designation 'Johnny Doe'. Are they the same person? Did they abide the same address? It they did, that meant they were the same person. This is Part of the cleansing process. It is notable because the customer signify will subsist off if the data is not validated. It may mess up the reports for marketing, sales and the finance departments.
The database has to subsist well designed to purge redundant data. The data has to subsist standardized and consistent. It moreover needs to abide business rules to process certain data. For example if the customer has an invalid zip code, should it subsist situation in the data warehouse or should it subsist situation in an mistake report until the data gets corrected. Meta data is one passage to standardize the data; it moreover documents the source of the data, where the data stores in the database, the definition of the data and the business rule of the data. In this way, the IT department can easily identify if the data is in the wrong database or comes from the wrong source; it can moreover account for the definition of data to the customer.
Business Intelligence Products
So now the company decides to build the data warehouse, how enact you find the right tool? First the company has to evaluate what RDBMS to utilize for the data warehouse. You abide to know how much data does the company have, how often does the company requisite to load into the data warehouse and how posthaste it needs to load the data. There are SQL Server, Oracle, Teradata, DB2, and others. The hardware, the communication links and the champion is moreover an notable factor to deem choosing the right database. After staid consideration, my company decided to utilize SQL Server 2000 for their data warehouse because of the size of their data warehouse and the cost. They moreover recognize ahead the original features of SQL Server 2005 and its integration with .NET for future development.
Then they abide to elect the ETL tool. There are a lot of ETL tools in the market, for example Ab Initio, Informatica Power Center, IBM WebSphere as well as splendid customary DTS packages in SQL Server. One of the data warehouse experts had said that the notable Part of ETL is that the people must understand the data. The best utensil is the utensil that you can retrieve and load the data efficiently and correctly and is the most cost efficient for the company. enact not just recognize at sum the fancy and expensive tools, evaluate every aspect. Is the utensil smooth to set up? Is the utensil smooth to learn to use? If it takes a developer six months to learn to utilize the tool, is it worth the time and effort?
I used Ab Initio to chase the same amount of data from Oracle 9i to SQL Server 2000 and at the same time I used DTS package to enact the same thing. The response time was almost the same. But Ab Initio costs a lot of money and DTS package is free. I am not adage Ab Initio is not a splendid product, if the company has to retrieve zillions of data everyday, it is definitely a splendid product to consider. Just liked I travel from situation A to situation B (approximately 10 miles) and I travel there driving a Honda Civic. It is cheap and reliable. At the same time I can moreover travel there driving a Hummer. enact I prefer a Honda Civic than a Hummer? Of course I would like to drive a Hummer if I am as flush as Bill Gates, but my bank account tells me a Honda Civic is splendid enough! But if I abide to drive up to Mount Rushmore in South Dakota in December, I may deem another vehicle. In my case they utilize splendid customary DTS packages and stored procedures to extract, cleanse and load their data warehouse and it is doing a very fine job.
A business intelligence utensil is used to serve the customers to access and anatomize the data in the data warehouse. After you build the data warehouse, then you abide to elect BI tool. It must subsist the one provide the most benefits to the business and match the business expectations. The utensil has to provide security and privacy of the data. The users can access it and learn to utilize it fast. If it does, then it is a splendid business intelligence tool.
