1.2 Skillset requirements for IBM Cognos Dynamic Cubes
To take advantage of Cognos Dynamic Cubes, three specific sets of skills are required:
modeling, Cognos administration, and infrastructure. A strong partnership with your database
administrator (DBA) can also contribute to a successful deployment.
1.2.1 Modeling
Cognos Dynamic Cubes is based on dimensionally modeled relational data that is structured
in a star or snowflake schema. As such, the key skill that is required to realize the full potential
of Cognos Dynamic Cubes is data modeling, including knowledge of star or snowflake
relational structures, and dimensional modeling.
1.2.2 Cognos administration
Because the dynamic cube technology is included with IBM Cognos BI, knowing how to
administer the Cognos platform and its multitiered architecture is required so you can
properly architect and deploy a Cognos solution that includes Cognos Dynamic Cubes. For
example, to set up a large Cognos Dynamic Cubes application along with other large
relational applications, advanced routing rules must be set up, which requires advanced
knowledge of the Cognos platform.
1.2.3 Infrastructure design
Cognos Dynamic Cubes uses modern hardware capabilities to maximize performance over
large volumes of data. Specifically, it relies on large memory spaces, and careful
