Divide and aggregate: caching multidimensional objects

A common optimization technique in the OLAP application domain is the use of summary aggregate data. For an appropriate support of analysis hot spots, we propose a query based aggregate cache of `multidimensional objects'. The major drawback of previous query caching methods is that new queries must be completely subsumed by a single cached object in order to
