Abstract
An On-Line Analytic Processing (OLAP) system identifies a plurality of simultaneously computable moving aggregate functions in a query. The identified moving aggregate functions are then partitioned into sets that can be computed simultaneously based on equivalent sort expressions. Finally, the OLAP system generates an access plan that executes the partitioned sets simultaneously.
