Chapter 4. Measures and Measure Groups

With our dimensions designed, we can now turn our attention to the cube itself. Taking the basic version of the cube that the 'New Cube' wizard built for us as a starting point, we'll want to add all the dimensions we've built to it, add data from more than one measure group, and make sure that the measures in our cube always aggregate up the way we want them to. In this chapter we'll take a look at the following topics in detail:

  • Useful properties to set on measures

  • Measure aggregation types and other functionality that affects how measures aggregate

  • Using multiple measure groups

  • Setting up the relationships between measure groups and dimensions
