Zusammenfassung:PROBLEM TO BE SOLVED: To provide a system and a method for proactively caching by using modified OLAP (on-line analytical processing variant). SOLUTION: MOLAP (Multidimensional OLAP) performance is leveraged for ROLAP objects (dimensions, partitions and aggregations) by building, in a background process, a MOLAP equivalent of that object. When the background processing completes, queries are switched from ROLAP queries to MOLAP queries. When changes occur to relevant relational object (such as tables that define content of OLAP objects), an OLAP object is switched back to a ROLAP (Relational OLAP) mode, and all relevant caches are dropped while, as a background process, a new MOLAP equivalent is created.
