Research and Design of Multi-Source Heterogeneous Information Integration Platform for Metadata Service

Abstract:

Based on metadata technique, this paper introduced metadata service oriented multi-source heterogeneous information data integration frame for large multi-source heterogeneous information integration management and interconnecting, intercommunicating, interoperability between different heterogeneous information systems. This metadata service oriented frame, benefiting from knowledge base of data warehouse, had 5 layers frame system including resource layer, integration layer, management layer, service layer and customer layer. Metadata service system contained data layer, directory service logic layer, data exchange layer and Web presentation layer. This paper represented that the metadata service was the core of integration frame, and the realization of integration management platform was feasible.
