摘要：Ontology Based Data Access (OBDA) is an emerging research area to query relational databases via ontology, to which these databases are mapped. The ontology depicts the conceptual representation of the domain of interest which along with data sources and corresponding mapping allows us to translate the SPARQL queries into the data level queries and executed by the underlying database management systems. This paper uses an open source OBDA system, called Ontop which is developed by Free University of Bozen-Bolzano, for querying virtual RDF graphs with SPARQL.
