基于XML Schema的数据库间信息交换技术

Data Exchange between Heterogeneous Databases Based on XML Schema

随着电子商务的发展和分布式数据库的广泛应用,异构环境间的信息交换变得日益重要。分析了XML在解决异构数据库集成问题中的优势,针对如何实现XML和关系数据库间的相互转换问题,提出了一种安全、有效的解决方案。该方案通过解析Schema文件,依据一定的模式映射策略,实现了数据库交换的跨平台操作。

With the development of e-commence and the widspread use of distributed database, the data-exchange between heterogeneours environment becomes more and more frequent. An effective and reliable solution to this problem is proposed, on the basis of analying the current technics. Access between heterogenous database can be achieved by template mapping between XML document and database schemas.
