【摘要】 良好的企业应用集成（Enterprise Application Integration，简称为EAI）是现代企业向电子商务转型的前提条件。传统的EAI解决方案主要从应用系统的数据层着手，对异构系统的数据源进行集成。这种方式存在几个弊病：首先，不能保证数据的完整性和数据约束性；其次，相互集成的各个系统之间的耦合度大大提高了,增加了集成系统的复杂度；再者，这种情况不利于企业向电子商务的方向转型。针对传统EAI解决方案中存在的问题，本文引入了一种新的技术——Web Service（又称为Web服务），利用它来辅助建设EAI。研究了利用Web服务实现对系统数据层和架设于数据层之上的业务逻辑的封装，从而实现异构系统之间松散耦合的集成。进而为企业向电子商务转型做好充分的准备。文章研究并给出了基于Web服务的EAI解决方案。最后，利用Web服务理论，解决实际中的一个问题。更多还原

【Abstract】 Well designed Enterprise Application Integration (abbreviated as EAI) is the precondition of the transplantation to the e-Business to the corporation. Traditional EAI solutions integrate different application systems from the data source layer. The are several disadvantage of these solutions: First, it cannot guarantee the integrality and restriction of the data source; Second, the relation of these integrated applications is enhanced, and this make the integrated system more complicated; Finally, this type of integration has no benefit for the corporation in transplanting to the e-Business.According to these problems, this article introduce a new technology — Web Service to help constructing EAI. Research how to encapsulate the data layer of the system and the business logic which constructed on the data layer, consequently realize the loose-related integration of different applications. Then get ready for the transplantation to the e-Business of the corporation. The article gives the EAI solution based on Web Service. In the end, use the theory of Web Service to solve an actual problem.TingLunBan(Computer Engineering)Directed by prof.KeQinLiu更多还原
