Abstract: An heterogeneous data integration enquiry system based on the Web Service is proposed, which uses B/S and C/S combination of multi-storey distributed architecture to improve the system’s practicality. The heterogeneous data and differences of system patterns are shielded. Simulation experimental results show this design scheme can achieve the fact that much more heterogeneous systems can be integrated, the functions of transparent user query are implemented, and the safety of the data source is ensured.
