A Framework of Semantic Schema Integration Based on OWL Ontology Mapping in Dart Database Grid
Qiu Ju · 2005
Brings forward a framework on how to integrate database schemas using OWL ontology mapping which is based on semantic in Database Grid. The framework adopts a two-stages mapping method as following, the first step is to implement local mapping, or couverting relational schema to RDF/OWL semantic schema; the second step is to implement global mapping, or bridging relationship between local data semantic and global sharable ontology. Essen- tially, heterogeneous database schema is represented clearly through ontology and integrated on the semantic Web layer. At the same time, it implements sharing and query based on semantic layer and keep both local and global on- tology mapping loose coupling which makes semantic query more flexible between across-database and single database.
