Research And Application Of Web Services In Enterprise Application Integration

With the popularization of Internet technology and the increasing demand of enterprise information construction, enterprises become more and more eager to realize the incompact coupling integration and interoperation among heterogeneous systems of multi-platform and multi-language under the background of Internet, which puts a new challenge to traditional EAI solution.Web Services as a new technology puts forward a Service-oriented distributed compute model, its main object is to build a common technology layer, above which different applications can implement the connection and integration with each other, so Web Services has become a new EAI technology under the background of Internet.The thesis mainly researches the application of Web Services in EAI, Firstly, it studies the history and layers of EAI, introduces two tradition solutions of EAI, and also analyzes their disadvantages, in the meantime, it discusses the advantage of EAI solution based on Web Services compared with traditional EAI solutions.Secondly, the thesis introduces the structure and key technologies of Web Services in detail. On the basis of which, it designs a kind of EAI framework based on Web Services, and analyzes the module functions of this framework.Finally, the thesis designs and realizes the key points of application of Web Services in EAI, including the dynamic transfer of service and encapsulation of legacy application, and it puts the EAI framwork on WebGPS system of some logistical enterprise in Liaoning to realize the application integration based on Web Services, which gets a definite effect.
