Role-playing Dimensions — 2 Comments

  1. I do not understand the physical implementation of role playing dimensions, but cannot imagine that you would safe much on processing time. As per your example each role playing dimensions’ members would still create its own tuple where data needs to be aggregated. (i.e. the group by processing concept would have to run for each one in any case).
    I have always understood that by creating role playing dimensions you are simplifying the project layout and the need to create each role playing dimension and its structure (hierarchies, etc.) separately. However, behind the scenes SSAS should create individual structures for each role playing dimension in order to aggregate properly.
