YAM/sup 2/ (yet another multidimensional model): an extension of UML

摘要

This paper presents a multidimensional conceptual object-oriented model, its structures, integrity constraints and query operations. It has been developed as an extension of UML core metaclasses to facilitate its usage, as well as to avoid the introduction of completely new concepts. YAM/sup 2/ allows the representation of several semantically related star schemas, as well as summarizability and identification constraints.
