Star schemas describe the structure and properties of multidimensional sources such as data marts and data warehouses. They have a simple structure and a predictable topology. We propose Star-Mod a representation of Star schema model described in UML and infer its instances from relational schemas. StarMod includes a comprehensive set of properties specific to multidimensional data with a view to its application in matching Star schemas. This paper demonstrates that in comparison to using the relational model, the quality of matching between Star schemas is improved if they are described using a more precise model such as StarMod, even if these Star properties are inferred from the relational schema. We demonstrate that StarMod can be also effective for matching arbitrary non-Star relational schemas.
