On the basis of studying the storage patterns of the OWL ontology and the existing storage patterns of ontology based on relational databases,this article proposes a new method of storing the OWL ontology based on relational databases.This method acts according to the structural word characteristics of OWL,designs a relation table to preserve the relations in the ontology between the resources,describes the features and constraints,depicts the levels and equivalence relations of ontology,saves the semantic information of ontology well.The method is suitable for storing large-scale ontologies,and simultaneously enhances the efficiency of searching,inquiry and mapping.
