基于模型驱动的XML与数据库双向映射技术

The Technology of Bidirectional Mapping Between XML and Database Based on Model-drive

XML(eXtensibleMarkupLanguage)不但是第二代Web的核心,同时也是异构应用数据交换的中性载体,基于XML的各种应用研究已经广泛展开。文章在比较XML和数据库各自特点的基础上,提出XML和数据库相结合实现异构应用数据交换问题,研究基于模型驱动的XML与数据库的双向映射方法,讨论双向映射过程中存在的问题,并结合典型例子,对该方法进行验证。为实现XML和数据库之间的数据有效传输提供所需的关键支撑技术。

XML (eXtensible Markup Language)is not only the core technology of the second Web but also the neutral carrier of data exchange among isomerous application,and diverse research works based on XML application have been widely taken out.This paper,first compare s XML with databases,and put s forward the opinion of combining XML with database to realize the exchange among isomerous applications.Then it also studies the bidirectional mapping technique between XML and databases based on model-drive,and discusses the possible problems.With the typical example,this technique is validated and it will lend deep-seated technical support to the data transformation between XML and databases.
