Abstract
A multi-dimensional table having plural dimensions is stored in a database system, where plural grouping combinations of the plural dimensions define corresponding subsets of the multi-dimensional table. An aggregate measure for each of at least some of the plural subsets is computed, where the aggregate measure for a particular subset represents a relationship of the particular subset to one or more parents of the particular subset. Less than all of the at least some subsets are selected to materialize based on the aggregate measures.
