ABSTRACT:
A database processor is provided for on-line analytical processing. The processor is arranged to obtain multi-dimensional aggregates of an input relation. Prior to aggregation, the processor performs a pre-processing stage in which the processor identifies Group-bys that are equivalent to the root relation and thus can be derived directly from the root relation without computation. In this manner, the computational time and storage of the multidimensional aggregates is reduced since only unique Group-bys in the lattice are computed and stored.
