An Research On Inter-department Application Integration Model Based On XML Web Service And Workflow

With the rapid development of internet technology, the extent of social information is improving day by day in our country. Especially popularized by all levels of governments, our governmental information construction has made quiet great progress. But as a whole, there are also many problems, for example, the business systems of different departments are doing things in their own ways, many of them are constructed repeatedly and do not communicate with each other, so they are difficult to promise information sharing and business collaboration. How to solve these problems has become an urgency for government to carry information construction into execution. This thesis sets the construction of enterprises' basic information exchange platform in import and export fields in Fujian province as a background, depending on the realization of information exchange and sharing among different departments' application systems, it also studies and discusses the problem that how to achieve the aim of governmental business collaboration through the information exchange platform. After analyzing several typical technologies that are relevant to this studying field and according to the character of this studying background, this thesis proposes a multi-platform and inter-department application integration model, which is based on XML, Web Service and workflow technology. This thesis makes a deep discussion on core technologies involved in the model and a detailed analysis of several key techniques which realize the model. In this model, XML is the unified standard of data exchange. We can solve the problem of heterogeneous information exchange in multi-platform by using XML as a carrier of information exchange because it is well-formed and platform independent. Every department's business systems exposed different functions are wrapper as web services. Based on XML and its serial of technologies, web service shields the difference of realization platform completely and all kinds of applications can operate each other by the standard protocol so that realize the application integration effectively and conveniently in inter-departments Using workflow technology based on service, Web services in Internet can be combined and integrated efficiently so that helps us to construct complex business process and realize the inter-departmental business collaboration. Finally, this thesis designs an implementary framework by using BizTalk as enterprise application integrated service platform and makes a stimulant example to verify the feasibility of this implement framework.
