With the establishment of more and more management information systems in the enterprises, many heterogeneous databases have been produced, resulting in the phenomenon of the information island. This paper puts forward a method based on ontology to integrate the heterogeneous databases and presents the framework of the integration method. In this framework A method based on relational database is presented to build the mixed ontology structure Common VocabularyLocal Ontology. The mixed ontology structure is used to establish the semantic web for enterprises. This novel approach exploits the multithreading combined with semantic web to implement parallel retrieval on an integrated platform. The application that this prototype system of the integration method has been implemented in a research institute verifies the method could effectively analyze the user's intention, thereby improving the reuse of knowledge.
