| Abstract: | In order to realize the target of data integration in heterogeneous environment, the executive plan of data sharing among enterprises＇ heterogeneous databases based on XML and B/S three-ply structure is proposed, and a general heterogeneous data integration system is designed and realized. The kernel structure, working process and modules＇ functions of the system are introduced. The design and realization of key modules, such as the validation and extraction of XML schemas, the mapping of inter-XML document, the mapping between XML document schema and database relation schema, are elaborated. Finally, the relevant Java technologies used to realize the system are briefly illustrated. |
