A study on ontology storage based on relational database

Ontology is the foundation of the Semantic Web, and the relational database is the most current data storage method on the World Wide Web, so the ontology storage research based on relational database is the one of the main problems. In order to achieve general storage of ontology data, make it easy to use the ontology data in the following application. This paper presents a model of storing Ontology in relational database on the basis of the existing ontology storage model, and the characteristics of OWL ontology language. The model structure is simple, stability, and easy to be understood. The experimental results show that the storage model in this paper has good scalability and query efficiency.
