The TreeScape System: Reuse of Pre-Computed Aggregates over Irregular OLAP Hierarchies
Very Large Data Bases Conference
We present the TreeScape system that, unlike any other system known to the authors, enables the reuse of pre-computed aggregate query results for irregular dimension hierarchies, which occur frequently in practice. The system establishes a foundation for obtaining high query processing performance while pre-computing only limited aggregates. The paper shows how this reuse of aggregates is enabled through dimension transformations that occur transparently to the user.dblp:conf/vldb/PedersenJD00 fatcat:24f6j5inmzbs5c6xaqyc4fwmwi
