The discussion of the importance ...

We describe the architecture of the OBDA systemOntop and analyse its performance in a series of experiments. We demonstrate that, for standard ontologies, queries and data stored in relational databases, Ontop is fast, efficient and produces SQL rewritings of high quality.
