Abstract: A relational database management system (RDBMS) for servicing query statements from one or more client machines, using a relational data store and a multi-dimensional database (MDDB). The RDBMS includes a query interface which is adapted to receive query statements from the client machines, and to generate one or more query requests. The RDBMS includes a query handling mechanism which receives each request from the query interface, extracts a set of dimensions associated with the request, uses the dimensions to retrieve aggregated fact data from the MDDB, and forwards retrieved aggregated fact data to the query processing mechanism for subsequent processing.

Abstract: Novel method and system for distributed database ray-tracing is presented, based on modular mapping of scene-data among processors. Its inherent properties include scattering data among processors for improved load balancing, and matching between geographical proximity in the scene with communication proximity between processors. High utilization is enabled by unique mechanism of cache sharing. The resulting improved performance enables deep level of ray tracing for real time applications.

Abstract: A system for supporting OLAP analysis over a network. The system comprises an OLAP server for enabling an OLAP user to perform OLAP analysis via interaction with a client machine on the network. The system also includes a data aggregation module comprising a multi-dimensional datastore, an aggregation engine integrated with the multi-dimensional datastore, and a first interface for loading base data from a data source to the aggregation engine. The aggregation engine performs data aggregation operations on loaded base data, generates aggregated data from the base data, and stores the aggregated data in the multi-dimensional datastore. A second interface receives requests for OLAP analysis from the OLAP server, accesses the aggregation engine to retrieve from the multi-dimensional datastore, aggregated data corresponding to requests, and communicates the retrieved aggregated data to the OLAP server for query servicing, in a manner transparent to the OLAP user.
