Design And Applications Of EAI Based On The Web Service

Along with the continuous development of enterprise informationization, different computer application systems in the enterprises are adopted in various hardware platforms and operating systems by applying different communication protocols, which has given rise to the data redundancy and overlapping functions and the difficulties in information transmission and resource utilization among different systems. Therefore, the research and development of the enterprise integration technologies under network environment has become an important issue for the enterprise informationization construction. This thesis will mainly analyse the following points:1. This thesis firstly gives a concise introduction to the background of enterprises application integration (EAI), and it puts the Web Service-based enterprise applications integration research as the goal of this study by comparing the advantages of the Web Service technology in the field of the enterprise application integration (EAI).2. This thesis analyses the architecture of Web Service system and its core technologies: SOAP, WSDL, UDDI and so on. On the basis of illustrating the relationship between the Web Service and EAI as well as canonically analysing Web Service, this thesis puts forward a framework of the Web Service-based enterprises application integration and introduces the main functions and the development process of this framework. The functions of the main modules will be the emphasis in this part.3.Based on the above-mentioned solutions to the application integration and network interface transformation project of CTAIS in Guangdong province, this thesis focuses on the detailed demonstration of the Web Service-based EAI model application in a unified data platform, and introduces the Web Service development process by implementing a simplified real-time charge of the Web Service.
