Paper Abstract:
|
On Line Analytical Processing (OLAP) is an approach to provide the answer to analytical queries. Pre-aggregation is one of the most important techniques used to speed up the query response time. However, if many aggregates are precomputed, then the database can quickly multiply in size. In this paper we present a scheme of how to decrease the storage size of a multidimensional data cube if you want to load preliminary calculated non-additive measure data into MOLAP database. We report some experimental results here. |
