Abstract

The current invention discloses methods for transforming a set of relations into multidimensional data cubes. A syntheses process is disclosed that dynamically and with minimal user input eliminates ambiguities when populating a data cube by introducing table-like virtual relations. The methods are generic and applicable to many data warehouse designs. The methods support relational OLAP for a wider variety of data and structures than possible using current relational implementation schemas.
