One of the most interesting usages of shared conceptualizations is ontology-based data access. That is, to the usual data layer of an information system we superimpose a conceptual layer to be exported to the client. Such a layer allows the client to have a conceptual view of the information in the system, which abstracts away from how such information is maintained in the data layer of the system itself. While ontologies are the best candidates for realizing the conceptual layer, relational DBMSs are natural candidates for the management of the data layer. The need of efficiently processing large amounts of data requires ontologies to be expressed in a suitable fragment of OWL: the fragment should allow, on the one hand, for modeling the kind of intensional knowledge needed in real-world applications, and, on the other hand, for delegating to a relational DBMS the part of reasoning (in particular query answering) that deals with the data. In this paper, we propose one such a fragment, in fact the largest fragment currently known to satisfy the above requirements.
