Ontology Based Heterogeneous Data Integration Framework Facing Mobile Environment

In the context of cloud computing, Mobile Data Integration Platform is put forward, on this basis, we first study on SORE (Simplied Object Repository) system of heterogeneous data integration based on CORBA. Furthermore, by virtue of the design of Heterogeneous Data Source Wrapper, this paper introduces an ontology based distributed information integration framework(OIIF), it implements uniform semantic query on heterogeneous data and enhances the depth and scope of available information. OIIF is innovation, its study has practical significance.
