Abstract
The paper introduces the concept of quotient relations to model and query OLAP
data. The use of quotient relation inherits the advantages of the original
relational model as it was introduced by Godd. Drill-down and roll-up
operations can be performed by the powerful partitioning and de-partitioning
operators on quotient relations. The proposed approach fulfills the
requirements for a formal data model, namely the existence of an implementation
independent formalism, the separation of structure and content and the
existence of a declarative query language.
