基于XML异构数据库查询与更新系统的探讨

XML-based Heterogeneous Database Query and Update System

根据XML的特点,提出了关于XML异构数据源的集成设计方案,借此弥补当前集成系统无法实现更新的缺憾,从而满足企业异构数据集成的需求。该系统的实际运作方式是将SXQuery查询设计成系统内部的查询树,将所查询到的数据提供给XQuery分析器,并且由此分析装置转换成XML视图。这种系统最大优势在于,可以为用户提供更为便捷的数据查阅服务。

Text based XML features,presented on the integration of XML heterogeneous data sources design,to make up the current system can not achieve more integrated defect,heterogeneous data integration to meet business needs.The actual operation of the system is designed to SXQuery queries within the system query tree,the query to the data available to Xquery parser,and the resulting analysis equipment into an XML view.Maximum advantage of this system can provide users with more convenient access to services data.
