The Value of Cognos Schematics

Cognos 11.1.5 (& newer) allows developers to incorporate custom schematics via scaled vector graphics, which are based on xml. This means that you can modify the xml of the graphic to create reference objects that you can use in order to align your data with parts of the graphic. Let’s step through some of the work that has to be done to make custom schematics work.

How to Save Report Outputs to a File System in Cognos Analytics

Oftentimes Cognos report output is needed to be consumed by many users in your organization. You could have them log into the portal and access the output directly but maybe you don’t have the time or expertise to be setting up users to access Cognos directly and then maintain all of those users. You could have the output emailed to them but you don’t want to clog up your mail server with hundreds of attachments. A good option could be to save the report outputs to your internal network or the cloud and have your users access them from there.

Join Query Optimization in Data Modules

Optimization of joined queries in Cognos Analytics is a useful way to improve performance by reducing the data returned by the database. Joins with one-to-many or many-to-one cardinality use key values from the table on the one side of the join to filter rows in the table on the many sides of the join. Like a developer who uses IN, BETWEEN, or a subquery in their custom SQL query, so can the Cognos query engine.

BI Tomorrowland

…As I stood there, rubbing my bruised noggin and craving Dutch apple pie, I reflected on the changes currently underway in the world of BI. The technology oracles have been saying it for some time now, but never had it been more apparent to me than at IBM Data & AI Forum last October that social forces, business practices, and new technologies are changing the way we think about enterprise data.

In this article, we look at how data visualization has evolved to effectively communicate important ideas in life-and-death situations such as the COVID-19 pandemic. Specifically, we examine the viral “flatten the curve” visual, as well as other visualizations that track the spread of the disease and the potential impact on our world.

Creating Custom Data Visualizations in Cognos 11.1.5

The ability to add your own custom visualizations came with Cognos 11.1.4 and has only improved in the 11.1.5 release. Being able to create or adapt an existing chart created with any JavaScript library means we're no longer tied to what IBM provides. If you see a chart in another tool that you like, then I'm sure there's a way to create it in Cognos.

The Power of Data Module Column Dependencies

When Cognos 11.1 was released, it introduced enough new Data Modules features that a realistic case could be made to consider moving from Framework Manager packages to data modules for metadata modeling. One of the essential pieces that were missing from earlier releases was the ability to deal with multi-grain issues (as addressed by determinants in Framework Manager). To address this issue, Cognos has recently added something called column dependencies.

Creating Custom Calendars in Cognos Analytics 11.1s

One of my favorite features of Data Modules since version 11.1 is the ability to easily do relative date analysis. What used to take a bunch of coding in Framework Manager or several queries within a report, you can now do by pointing your measure to a calendar in a Data Module and automatically have several relative time data items and filters available.
