MQL: a mapping management language for model-based databases

Résumé

Nowadays model mapping plays a crucial role in applications manipulating various heterogeneous sources (data integration and exchange, datawarehouse, etc.). Users need to query a given data source and still obtain results from other mapped sources. If many model management systems have been proposed that support highlevel operators on model mappings, a more flexible approach is needed supporting the querying of mapping models and the propagation of queries through mappings. As a solution, we present, in this paper, a mapping based query language called MQL (Mapping Query Language). MQL extends the SQL language with new operators to exploit mappings. We show the interest of this language for the multi-model ontology design methodology proposed in the DaFOE4App (Differential and Formal Ontology Editor for Application) project.
