基于XML与J2EE技术的数据交换中心的设计与实现

Design and Realization of Data Exchange Center Based on XML and J2EE

为实现在异质异源数据库间的数据交换,使用户可以透明地访问数据,提出一种建立数据交换中心的解决方案。在该数据交换中心的构建中,综合采用了XML,J2EE,XSLT等技术。通过使用XML作为数据的载体,运用XSLT样式表对XML进行转换,并使用反射机制调用EJB中的业务逻辑以使得数据交换节点之间方便地通信。最后,基于此思想,设计并实现了该数据交换中心,在某大学校园网中进行运用,收到了良好的效果。

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.
