Chapter 5. Modeling Dimensional Data

This chapter will cover the use of dimensional modeling, which is more correctly called Dimensionally Modeled Relational (DMR) data. The dimensional models created can be used with IBM Cognos Analysis Studio, and also with the other studios.

In this chapter we will cover the following:

  • Creating regular dimensions

  • Creating regular dimensions with multiple hierarchies

  • Creating measure dimensions

  • Creating scope dimensions

By the end of this chapter, you will be able to create a dimensional data model using relational data sources.
