If you’ve found this blog you’ve likely already felt the deep sting of incomprehensible Cognos IT acronyms. Fear not – I am here to deliver the soothing balm of jargon clarity. Behold, the IBMBV Cognos Glossary of Terms!
Cognos Analytics: Cognos Analytics (also known as Cognos 11) is the newest version of IBM Cognos, released in December 2015. Cognos Analytics features a completely modernized UX with a host of new self-service features, including web-based data modeling, intuitive dashboard creation, and visualization via search that bring Cognos functionality in-line with current demands for analytics solutions. Cognos Analytics also maintains its enterprise class pedigree by retaining proven technology like Framework Manager & Transformer while providing a smooth upgrade path for Cognos BI content. It is available in on-premise and cloud deployments. See What Is Cognos Analytics for more information.
Cognos BI: Cognos BI (also known as Cognos 10) is the previous version of Cognos, released in November 2010. Cognos 10 retained the functionality of Cognos 8 while adding significant new features, including Workspace and Workspace Advanced, the 64-bit Dynamic Query Mode, and Dynamic Cubes. As of this writing (October 2016) the vast majority of Cognos customers are on some version of Cognos 10. IBM has announced end of support for Cognos 10 as April 30th, 2018.
Cognos 9: Hahaha! Good joke Ryan! There was no Cognos 9!
Cognos 8: Cognos 8, released in September 2005, combined a variety of existing software into an enterprise BI environment with content hosted in the web rather than client side. The bedrock components of Cognos – Framework Manager, Transformer, Report Studio, etc… were either created for or incorporated into Cognos 8.
Dynamic Query Mode (64-bit): Dynamic Query Mode (DQM) is a 64-bit query execution engine introduced with Cognos 10. Through a combination of in-memory aggregation/member storage and the inherit advantages of x64 applications DQM significantly improves query performance vs the previous query engine (CQE). Keep in mind that the advantages of DQM are best realized in Dynamic Cube or DMR packages – pure relational may or may not experience much benefit from DQM.
Cognos Query Engine (32-bit): Cognos Query Engine (CQE) is the 32-bit query execution engine with which Cognos has shipped since at least Cognos 8. It’s a safe bet that most existing Cognos content executes via CQE as it is the default execution mode in Cognos 10. CQE will receive only bug-fixes going forward as all new development efforts are focused on DQM.
Data Modules: Data modules are a feature introduced in Cognos 11 that offer a web-based data modeling and blending experience. Data can be pulled from a large number of databases as well as excel files and Cognos packages. Key features include automatic relative time (YTD, MTD, etc…), table split/merge, custom grouping, data cleansing and multi-fact and even multi-database query aggregation.
