A paradigm shift in OLAP modeling

Panos Vassiliadis, Patrick Marcel.

Summary

In this line of work, we structure a vision for the Business Intelligence of the near future in terms of a model with novel concepts and operators. We envision systems where the end-user requests information at a very high level, expressed as his intention to discover information, and the system transforms this request to the concrete execution of algorithms in order to compute, visualize and comment data and important highlights among them as an answer to the information request made by the end-user.
