An Architecture of the XQuery System based on Virtual XML
一种基于虚拟XML技术的XQuery查询器系统框架

Based on idea of virtual Web page for the HTML page6], this paper proposes firstly a concept of VXMLF (Virtual XML File) , which separates the structure of XML file from the content of that. By means of modifying data model and query language of Xquery proposed by W3C, the paper gives an architecture of XQuery system based on virtual XML. Comparing with the original system, this query system has many new characteristics and advantages such as simplifying memory process, easy to maintain consistency of data, optimization of query computation and simplifying user operation.
