Research And Implementation Of Enterprise Application Integration Based On Web Services

At present, Web Services, Which is known as the third revolution of information technology in computer field, has increasingly appear to be marketable, while the software sector are preparing to burst into a great change. The development in Web Services technologies is to spur growing and completing of the Web Services applications. While the application mode of Web Services useful for commercial use both in providing a guidance and prompting the popularity.Traditional EAI technology is confined to software development mode and system integration methods, which lead to compact coupling among enterprise application system, and blocks enterprise's system upgrade and development. Besides, traditional EAI technology focuses on information currency and share inside enterprise and sustains application integration among enterprise poorly, while can not fit for extremely heterogeneous network environment and increasing demand of EC. With characters of protocol currency, platform independency and language independency, Web Services will fetch up to EAI.A EAI solution based on Web Services is proposed, and combine the platform of enterprise application integration----Biztalk Server 2004, a example about enterprise in and out application integration is gave. Concretely, main works are:1.We research and discuss the technology of Web Services ,and also discuss other technology involved such as XML,SOAP,WSDL and UDDI.2.We reseach and discuss the technology of the platform of Microsoft's the latest enterprise application integration----Biztalk Server, and also discuss other technology about enterprise in and out application integration, practise an example of enterprise application integration.3.There is much exchange of the data in enterprise application integration, and the data with XML to show, so design a XML data unify the platform to exchange data conveniently.4.There is much exchange of the data in enterprise application integration, so its' response speed great request. Because the Web Services transmit data with the SOAP, accelerate the response speed of the SOAP by compressing SOAP extension to improve the performance of Web services, and test it. 5.Web Service need much time to carry out, and deal with complex service on client, so it spends more time. It adoptes the caching to save the result of client's request temporarily, to optimize the efficiency of the Web Service.
