Yue Ping Cui, Ping Gu · Advanced materials research · 2013
Along with the increase of XML applications, Native XML database technology is gaining the attention of the field of database, and query optimization is still one of the key research contents. This article，from a new perspective, represents the research on the relationship between XML nodes and proposes a query optimization model based on the associated elements of XML data file . In order to query the information of the related elements in the XML data file, this method takes the strategy of index; and proposed the query algorithms on the query optimization model based on associated elements.
