In education support system research, the resources based on Web are the component databases, which are distributed by the education organizations. They are autonomous in management and heterogeneous in data model. The goal of our research is to provide the developers and uses with an integrated view and uniform interface of all the component databases. A composite 5-layer architecture including application, WWW server, event processing, driver interface and databases is presented. In addition, some key issues such as global data dictionary and uniform name service are discussed in this paper. The experiments show that the architecture and technology is feasible and practical.
