基于XML的异构数据交换技术及其Java实现

HETEROGENEOUS DATA EXCHANGE BASED ON XML AND ITS IMPLEMENTATION IN JAVA

所谓异构数据交换是指异构数据处理环境下不同数据源之间的互操作。EDI等传统的数据交换技术具有格式不灵活、成本昂贵、交互性与实时性差等缺点。本文讨论了XML适于异构数据交换的特点 ,研究了XML与数据库的交互技术 ,给出了实现XML与Oracle数据库交互的Java代码。通过JavaServlet方式实现了基于XML的异构数据库通信 ,在实际应用中运行良好。

Heteroigeneous Data Exchange is the technology of interaction between different data sources under heterogeneous data processing environment.The traditional data exchange technologies such as EDI have many defects,such as fixed format,expensive cost,limited interaction,limited realtime property,etc.This paper discusses the specialities which makes XML be good at heterogeneous Data Exchange,studies the mothod of interaction between XML and database,and provides example programs written in Java to exchange data between XML and Oracle database.we Implement an application of data exchaging based on XML using Java Servlet in a practise system and it runs well.
