14. The method as claimed in claim 13 , wherein creating, by the computer system, definitions of identifiable non-overlapping segments for the given base set of members in the multi-dimensionally modeled data source comprises: receiving user input relating to segmentation rules; and defining the segmentation rules based on the user input.
13. A method of using a computer system programmed to manage segmentation of a set of members in a multi-dimensionally modeled data source, wherein the multi-dimensionally modeled data source comprises an Online Analytic Processing database, the method comprising: creating, the computer system, definitions of identifiable non-overlapping segments for a given base set of members in a multi-dimensionally modeled data source, dividing, by the computer system, the base set of members into the segments based on the definitions of the segments; and using, by the computer system, the segments as objects.
