| Zusammenfassung: | The present invention relates to a system and method of optimizing execution of a distinct count query. The system and method allows clients or database administrators to improve queries by properly designing data cubes and partitions of the data in the cube. The partition data can also be ordered so as to facilitate determining the range of each partition. Partitions with overlapping ranges can be executed in parallel. Furthermore, partitions with non-overlapping ranges can also be executed in parallel to optimize query execution rather than digressing from parallel to sequential execution by virtue of their range. |
