In order to improve business by automating business processes that span these isolated systems, the enterprise needs to integrate the isolated systems and applications with Enterprise Application Integration (EAI), which would be linking diverse systems and applications of the enterprise to enable the enterprise to adapt to the dynamic business environment. Whereas, with traditional EAI solution, it is difficult to efficiently link the different proprietary applications and data sources, and difficult to enable the system to rapidly identify and respond to changes in the dynamic business environment. This paper discusses the traditional EAI technologies and the bottlenecks for applications integration, also elaborates the Web Services technology and the advantages suited for applications integration. Therefore, the model of EAI with Web Services (EAIWS) is proposed to efficiently implement the integration of diverse applications and systems within or between the enterprises. With EAIWS, this paper provides an example to explain how the application system works. This paper also discusses the advantages of EAIWS.
