Research Of Key Technique Of Data Exchange Layer Based On SOA

Today most enterprises are confronted with a mission of enterprise application integration. To accomplishing this mission the fundamental precondition is implementing data exchange between heterogeneous systems. Traditional ways of data exchange always have some problems because of the limitation of its topology structure and compatibility. As SOA is widely used now, data exchange techniques are becoming to have a new foreground.This paper interpreted the concept and structure of SOA, then brought forward a data exchange layer model based on SOA after a deep research on criterion of Web Service and XML. The frame of the model was designed in the paper, using Web Service as a basic unit to implements all the modules and using XML as a medium of data exchange. It kept a loose coupling among the heterogeneous systems and a universality of the way of data exchange. Solutions of schema match and exchange between XML schema and relation schema and the reliability of SOAP message transmitting had been given in this paper. In the last, the experimentation and the application in project proved feasibility and practicability of the data exchange layer model.
