document: Bridging the gap between OWL and relational databases Schema statements in OWL are interpreted quite differently from analogous statements in relational databases . If these statements are meant to be interpreted as integrity constraints ( ICs ) , OWL 's interpretation may seem confusing and\/or inappropriate . Therefore , we propose an extension of OWL with ICs that captures the intuition behind ICs in relational databases . We discuss the algorithms for checking IC satisfaction for different types of knowledge bases , and show that , if the constraints are satisfied , we can disregard them while answering a broad range of positive queries .
