Abstract
A method, apparatus, and article of manufacture for the incremental maintenance of summary tables with complex grouping expressions where the change (insert/delete/update) of a single row of the base data can affect multiple rows in the summary table. The invention applies the complex grouping expression to the raw delta, yielding a delta stream consisting of multiple (but distinct) grouping combinations. The invention then inserts/deletes/updates delta values into/from the existing summary table so that each grouping combination of the delta stream modifies its corresponding grouping combination in the summary table.
