基于查询的XML数据库设计

摘要

随着---XML半结构数据的使用日益增加，处理超大型数据集时，查询效率可能是个问题。就这个问题，首先探讨了XML、XQuery及原生XML数据库的关系，然后给出了设计原生XML数据库的一些原则，其恰恰与关系型数据库相反，然而，在存储介质不再是信息瓶颈的现在，这些准则对提高查询效率有着重要的意义。%With the growing use of XML(semi-structured data), the query efficiency may be a problem when handle super data set. For this problem, this paper disscuss the relationship of XML, XQuery and native XML database firstly, and then some design principles of native XML database is given which is precisely the opposite with relational databases. However, in the information storage medium is no longer present a bottleneck, these principles to improve query efficiency of great significance.
