The Application Research Of Web Services In System Integration

Along with the enterprise business expanding, enterprise's systems become more and more. In order to new systems harmonious with old systems, we import the system integration, which can make many systems handler businesses and share information as a whole. The traditional integration solutions generally use technology like CORBA, DCOM and RMI to realize the point-to-point integration. But these solutions not only cost high but also the efficiency is low. Moreover, system integration often needs to solve the problems of language difference and platform difference in the distributional environment. But system is coupled tightly by traditional distributed technology, and can't solve these problems.At the same time, the Web Services based on WSDL, SOAP, UDDI and so on, is rapidly developing. All standards of Web Services are in the XML foundation, Web Services can be easy to solve the problems of integrating systems. So, this paper studies the system integration from Web Services.There is 5 parts in this paper. The first part introduces background and situation abroad and home. The second part generally introduces Web Services and the relationship between Web Services and system integration. Then we introduce the data integration, the function or the method integration and the business flow integrated. And latter two sides are the key points of this paper. The section of the function or the method integration mostly realizes the the integration of J2EE and the.NET. The section of the business flow integration mostly introduces the static integration and the dynamic integration from BPEL4WS and OWL-S.The innovations of the paper include:realizing the system, which integrates J2EE and.NET by Web Services; bringing forward the scheme, which realizes Semi-automaticIntegration of Web Services by OWL-S.
