Study of web services asynchronous invocation mechanism in information resource integration

With the development of educational information, the major concerns of the university are how to manage the current dispersed information unitedly and how to realize seamless share between information systems. This paper studies using web services to implement service-oriented architecture, puts forward data share model frame based on web service and XML technology, introduces the achievements of information systems share through combining the bidirectional options for the graduation designing, presents particularly the effectuation of asynchronous web service invoke based on event-driven, analyzing efficiency accordingly. The system share model resolves the problems on integrated confirmation of heterogeneous systems in campus network, fully considers the security and extension of the systems, providing excellent reference model for information contribution of the campus network.
