Research On Enterprise Application Integration Based On Web Service

The rapid development of Internet technology has put forward higher request for the enterprise information construction. ERP, CRM, SCM and e-commerce on the basis of the advanced management idea have become the developmen trend of enterprise application.

At the same time because of the difference of platform, developing language and communication protocol among applications has make enterprise application integration become an important subject of enterprise information construction.Firstly, the paper briefly introduces the background of enterprise application integration, analyzes the traditional distributed compute technology solution, such as DCOM, CORBA, RMI etc, and their defect. At the same time the paper discusses the advantage of web service technology in EAI contrastingly, confirm that enterprise application integration based on Web Service studying is the research target of the paper.Secondly, the paper introduces the characteristic and operation principle of web service technology system in detail. On the basis of basic principle of the introduction, designs a kind of eai architecture model based on Web Service, through service's definition, deployment, finding, binding, call etc. And the paper also simply discusses the data exchange question in eai, structure one data exchange model based on XML technology in eai.Thirdly, the paper references the schema model the paper brought forword, based on the demand of Tianjin One Limited Corporation as background, combine the concrete practice of enterprise's Budget Information Process System. Considering the fact demands, integrates enterprise data separated in each isolated enterprise system, structures a shown platform of enterprise's synthetic data, achieves enperprise information integration by web service technology, and makes a good foundation for enterprise's decision support. Now the system runs well, reaches the anticipated goal.Finally the paper points out the shortage of the paper and content of the next research.
