Abstract
A method, apparatus and program storage device for optimizing a query in a relational database management system is provided. The query including aggregate and grouping functions. An application table is preferably located in a source site and an aggregation operation is performed from a target site. After an initial aggregation operation performed from the source-based application table, the further aggregation operations are incrementally performed, by aggregating only the newly inputted relational database data into the target-based base aggregates table. This procedure allows the transformed query to perform more efficiently than the original query, while providing same results.
