Abstract: We present our approach for extending the OLAP model to include treatment of value uncertainty as part of a multidimensional model inhabited by concepts and non-rigid hierarchical structures of organization. New multidimensional-cubic operators defined over the IF-Cube are introduced. The emphasis is on operating over data with imprecision either in the facts or in the dimensional attributes organised in the form of kind of hierarchies.
Keywords: Generalized nets.
