| In recent years, with the constant development of enterprise's informationization, there are more and more information systems implemented and operated inside enterprises. Databases that these information systems use may be different, their developing instrument and running environment may be different. So "detached islands of information" are produced among different information systems, and they make enterprise's different department's systems unable to work in coordination. In such cases, the appearance of EAI technology brings first line dawn for destroying "detached islands of information". EAI realizes the not sewing and integrating of business function through sharing and exchanging the data among different systems. Web Services are to be putted Internet in, to go on reusable components that transfer through Web. It can convenient to implement EAI solution.This text is directed primarily to the question of" detached islands of information " during enterprise's informationization course at present, puts forward EAI system based on Web Services-WS-EAI. It has advantages such as fluffy coupling , supporting , very integrated ability of height of the trade ,etc. This text mainly discusses Web Services technology and EAI technology, and some relevant technology such as XML, SOAP, WSDL, UDDI technologies and .NET technology ,etc. On this basis, we analyze , design and develop WS-EAI software. First of all, design system architecture based on three layers; Secondly, analyze the demand of the system through object oriented technology(UML);Finally, realize XML Web Services, and use Web Service to realize the integration of the different databases, the integration of the business logic layer. This text provides WS-EAI software demanding analyzation, designing and course that realizes EAI systematically in detail. We apply WS-EAI to building in this project of integrated platform of informationization of mechanical manufacturing company. It has made certain application result. |
