Database management system having data aggregation module integrated therein

摘要

An improved method of and apparatus for aggregating data including a high-performance aggregation module (comprising a scalable multi-dimensional database (MDDB)) that is integrated into a database management system (DBMS). The DBMS includes a relational part comprising a relational datastore storing data in tables and support mechanisms. Bi-directional data flow occurs between the relational part and the integrated aggregation module whereby data stored in the relational datastore in loaded into the aggregation module and aggregated data stored in the MDDB of the aggregation module is communicated to the relational part. The improved DBMS can be used to realize achieving a significant increase in system performance (e.g. deceased access/search time), user flexibility and ease of use. The improved DBMS system of the present invention can be used to realize an improved Data Warehouse for supporting on-line analytical processing (OLAP) operations or to realize an improved informational database system, operational database system, or the like.
