In this paper we present an approach of RDF graph generation from relational databases. This approach consists of structures creation of ontology including classes, properties, hierarchy, cardinality and instances creation. This approach not only saves efforts in developing the Semantic Web but also makes an amount of data in relational databases machine understandable for the Semantic Web. The experimental results show that the approach is feasible and efficient, and is implementable with Java language.
