With the rapid development of computer technologies, especially in Internet aspect, lots of Management Information Systems based on computer technologies have been accomplished in almost every organization. Due to some relative independence between departments in enterprise, and short of consolidated plan and standard when designing application systems, there must be some information islands in the application systems, which are separate, heterogenous, obturated and unshared. Along with the fierce competition between enterprises and rapid info-innovation in enterprise interior, more and more communication between departments must be considered, in order to harmonize businesses, improve work efficiency and upgrade enterprise competition strength. Communication must occur by exchanging information, via application systems, so it's more and more important and frequent to share resources between application systems. Therefore, in order to share the resources more rapidly and conveniently, it is crucial to integrate information systems and to solve the problems about information islands.EAI is one of methods to solve the problem. EAI can help connect information systems, exchange data and deal with information between all kinds of application information systems, to relieve information obstacles in business process. Through integrating and optimizing different application systems and different business units, the scope of enterprise business or supply chains will get conformity. WebSphere is relatively successful application way, but it costs more. As far as the small and medium enterprises are concerned, the integration level will always be considered at data layer, so that it can directly access data and avoid logical business, moreover, it's lower cost and less difficult to integrate and perform, if only to stress the information resources needed between the different application systems.Considering the large amount of small and medium enterprises and limited capital, it's the key to seek a simple, efficient and low-cost method, to share data between different systems, to enhance enterprise automation further and to improve efficiency and profit.This paper starts from the deep research to data integration involved technologies.
