摘要
异构数据源间的数据共享是数据库研究的热点和难点.分析了当前信息发布技术的局限,以及现阶段应用XSLT、XPath和DOM查询XML数据的可行性;提出了一个应用模型,并用一个实例说明编程方法;介绍了使用XSLT技术来解决数据转换问题,使用Java将其封装为中间件.该中间件可以方便地移植到需要数据转换的软件系统中,解决了软件产品中关系型数据间的数据共享问题.
Data sharing in heterogeneous data sources is very hot and difficult in the study of The paper analyzes the limitations to issue info and the feasibility to currently apply XSLT, Xpath, for XMLdata. Then it gives an application model and illustrates the programming methods with an database field. DOM to search example. Some introductions are made of XSLT technology to solve the data exchange problems and a middleware is made by Java. The middleware can be conveniently transplanted into the software system which requires data transference and it solves the problem of data sharing.
