An ontology is an explicit specification of shared conceptualization.#R##N#The Web Ontology Language (OWL)#R##N#is a family of knowledge representation languages for#R##N#authoring ontologies, and is endorsed by the World#R##N#Wide Web Consortium. The main operation on ontologies#R##N#is to query them and to store them so as#R##N#to answer queries efficiently. By mapping ontologies#R##N#to relational databases, we can leverage the power of#R##N#SQL for ontology reasoning over millions of instances.#R##N#We address the problem of efficiently mapping and#R##N#querying OWL ontologies using relational databases.#R##N#We present an OWL ontology mapping tool, called#R##N#TRANS which can automatically map OWL ontology#R##N#to mapped relational schema. Using TRANS, we#R##N#answer both extensional queries and some intentional#R##N#queries. We compare our approach with schema-aware#R##N#OWL-mapping tool, Genea.
