随着计算机技术与Internet的普及应用

数据库应用得到飞速发展。然而在计算机应用领域不断优化升级、更新换代和整合时

异构数据环境下的数据很难得到重用

形成不利于数据共享的"信息孤岛"。本文以XML(可扩展标记语言)作为异构数据交换的载体

采用Java平台环境J2EE和Java开源库Dom4j实现异构数据交换的方法

有效地解决了异构环境下关系数据库数据交换问题

在保证完整性的前提下

为用户提供灵活和低开销的异构数据管理方案。

With the development of the computer technology and the Internet

the application of databases is developing rapidly. However

in the field of computer applications where everything is being continuously optimized

upgraded

and integrated

it is hard to reuse data in a heterogeneous environment.This forms information islands. Based on XML

which is the carrier of heterogeneous data for data exchange

adopting the J2EE and Dom4j technology

we solve the problem of data exchange for relational databases in a heterogeneous environment effectively. By guaranteeing integrity

we provide users with a flexible and low overhead method for heterogeneous data management.
