Enterprise Application Integration(EAI) Based On Web Services

At present, companies use computers more and more general. Most companies have a heterogeneous environment of disparate systems, which lead to many "information isolated islands". With the pressure of a competitive business environment there are more and more the needs to share data in business processes over different systems. In other words, these disparate systems should be integrated. That is the EAT dose.Traditional Enterprise Application Integration (EAI) methods usually integrate applications from peer to peer . which has many deficiencies, such as poor ability of integration, poor extensibility, poor interoperability and high cost in integration. Nevertheless, Web Services has the predominant features of interoperability, encapsulation, low cost, loose coupling structure, normal protocol and high integration, so currently integration schema of EAI based on Web Services has becoming the leading EAI field.Passing analyzing some traditional and representative enterprise application integration frame, combining the 863 project: ASP platform orienting network manufacture of middle and small enterprises, puts forward an EAI Model Framework(WS-EAI) based on Web Services. The WS-EAI frame based on Web Services is provided to build a middle layer which has nothing with any platform and language, so it can make the enterprise applications integrated together without gap and develop, publish, discover and bind all kinds of applications dynamically and quickly by loose-couple and low-cost way.
