基于XML异构数据集成研究

Research of Heterogeneous Data Integration Based on XML

针对目前数据库系统的数据存储在不同的系统中,且呈现分而不聚、聚而不合的问题,提出了以平台无关性的XML为核心交换格式的基于XML的异构数据集成方案,分析了异构数据集成的过程,设计并实现了数据库到XML文件的转换和基于XQuery的XML文件查询等功能,并提供了可视化的XML文件操作界面,实现了异构数据源的集成。

Aim at the state of current database applications that the core data are stored in different systems and are discrete, distributed and heterogeneous, a XML-based heterogeneous integration program, using XML as the core exchange format, is put forward in this article, and the integration process of heterogeneous data is analyzed. The conversion from database to XML file and also the query of XML file based on XQuery is designed and implemented. So the integration of heterogeneous data sources is implemented.
