摘    要：互联网应用广泛,Web上数据库信息发布和检索量迅速增加,而传统的数据模式不能满足Web的需求.为此,针对XML的优点,结合关系数据库的成熟技术,将XML数据模型映射到关系数据模型;此外,研究了存储策略及查询方式,提出了基于这种存储和查询方式下的Web信息发布和搜索模型.实践结果表明,该模型统一了存储和查询方式,实现了互联网上资源的统一,较好地解决了目前web检索结果准确性和相关性不高的问题.

Abstract: With the development of Internet, information publishing and retrieving become main problems. In this paper, the authors combine the perfect technologies of rational database, turn XML data model into relational model and discuss the method of XML storage and query in relational database in allusion to the merits of XML , then propose the information publishing and retrieving model based on this method. It u-nifies the model of storage and query and realizes unification of resource on Internet, so it can solve the problem, that is, correctness and relativity of retrieving results are not very ideal.
