Semantic Integration of Relational Database Based on Metadata
Baoping Yan · Jisuanji gongcheng · 2008
This paper proposes a metadata based approach for semantic integration of relational databases, through which relational databases can be dynamically translated to virtual Resource Description Framework(RDF) views according to a domain ontology, which enables both people and machine to understand and process the smart data. It introduces the semantic integration framework, analyzes the semantic mapping principle from relational databases to domain ontology, and gives the metadata model and approach to decompose and translate semantic query to distributed relational databases query. The implementation of a prototype is also introduced.
