Cohabitation of Relational Databases and Domain Ontologies in the Semantic Web Context

Despite the fact that database technology is mature, it is not yet compatible with Semantic Web requirements, such as Semantic Web language concordance. On the other hand, ontology technology is the most promising solution for concretizing the Semantic Web vision; however, it has not been recognized as the Semantic Web data model thus far. This paper aims to bridge the gap between ontologies and databases in the context of the Semantic Web by highlighting their advantages and disadvantages, their complementarity, and the most popular means of their mutual conversion.
