摘要
XML已成为互联网事实上的数据表示标准,在数据交换和数据仓库中广泛应用。但XML文件特征不能保障数据的安全性和并发访问,而RDBMS严谨的关系理论和技术的成熟性可以弥补XML技术的不足。结合XML与RDBMS的优点,提出一个基于RDBMS的XML数据存取方案,用于简化XML数据的管理和数据仓库的构建。利用Oracle XML DB技术实现XML在关系数据库中存储、更新和检索操作,使用户能透明地通过RDBMS来管理XML数据,相对于映射策略的数据转储方式,明显提高了XML数据存储效率。
XML has become the data representation standard on Internet,and widely used in data exchange and data warehouse.But the file characteristics of XML cannot guarantee the security of data and concurrent access and the precision of RDBMS theory and maturity of RDBMS can be achieved fast and concurrent access to data.The paper combines the advantages of XML and RDBMS and comes up with a XML storage resolution based on RDBMS to simplify the management of XML data and data warehouse building.It allows users to manage XML data based RDBMS transparently by using Oracle XML DB,relative to the middleware method mapping strategy.It can significantly improve the efficiency of the XML data storage.
