XML是万维网数据传输的主要渠道，有关XML映射到关系型数据库系统的研究已成为当今最重要的话题之一。映射方案对XML的处理效率具有一定影响，表现在以下几个方面：数据库可扩展性、数据在数据库系统的存储速率以及数据库里的信息存储模式。对一种高效的新型XML映射技术s-XML的性能展开深入探讨。研究结果表明,与现有相关方法如Edge和Attribute相比，s-XML的文档存储效果更理想。%XML is the main channel of the web of data transmission, research on mapping XML to relational database system has become one of the most important topics in the current era. Mapping scheme has certain influence on treatment efficiency of XML. It is shown in the following aspects: database expandability, the data storage rate and information storing mode in the database system. An effective and new XML mapping scheme technology, the s-XML is discussed in this paper. The results show that compared with the existing methods such as Edge and Attribute, document storage effect of s-XML is more ideal.
