Abstract
A process combines multiple grouping sets into single rollup sets with depth lists defining the levels of grouping that must be performed. Grouping sets are identified that are contained within other sets and combined into single rollups with depth lists. Cube aggregation conversion to rollup aggregation is provided for optimizing database query processing. Natural sets of rollup hierarchies within a cube are recognized and the cube is converted into those rollup hierarchies. Once converted, the rollup aggregation is performed to significantly reduce required processing.
