摘要
XML逐渐成为Web上数据表示和数据交换的标准。随着Web上大量的数据用XML文档表示出来,有必要对这些XML文档进行存储和查询,目前大多数商业数据库产品都支持对XML文档的存储、查询、索引等操作。本文讨论了在ORDB中存储XML文档时所涉及的存储技术,比较了三大商业数据库产品(IBMDB2,Oracle9i,MicrosoftSQLServer2000)在存储XML文档时所采用的方法。
XML has grown to the standard of data representation and data exchange on Web.With a large amount of data represented in XML documents on Web,it becomes necessary to store and query XML,and now,nearly all commercial database products have supported to store,query,and retrieve XML documents.This paper makes a survey of XML documents storage techniques in ORDBs,and compares the storage techniques employed by 3 major commercial database products,i.e.IBM DB2?Oracle9i and Microsoft SQL Server 2000.
