Design and Realization of Data Exchange Center Based on XML and J2EE
基于XML与J2EE技术的数据交换中心的设计与实现

In order to realize data exchange between databases which are of heterogeneity and to make it possible to access data transparently, a solution of constructing data exchange center is put forward. In the course of constructing this data exchange center, we use XML,J2EE and XSLT compound. To communicate conveniently between data exchange nodes, we use XML as the carrier of data, apply XSLT to transform the XML, and make use of reflection mechanism to invoke the business of EJB. Finally, based on this concept, we design and implement the data exchange center, and apply it in the CWISs of some university, and then it works well.
