Based On XML Graphical-inquires Conversion Technology Research And Application

With the development of science and technology, the progress of The Times, Computer technology and network technology developed fast, the network data exchange becomes more and more frequent by enterprises and individuals, XML become the standard of data description and data exchange, more and more data do storage and exchange in XML form, a large number of XML documents appear in the current network. Since XML since the advent, immediately become Internet data exchange and data representation new form, by many people's attention. Many industries are using XML to describe data information. XML query technology research is the current XML database research a hot issue. More and more data appear in the current network, among many enquiry systems, Xquery form becomes more and more mature, and then it provide different forms of support varying degrees, the grammar of it is very strong, while for general users, enquiry system is still complex, XML-GL language is also a hot direction for enquiry technoloy, and its main character is that its graphical interface can easily be understood and accepted. And it can make the difficulty lower of enqury languge. And it make it convinent for most users to enquiry.The major objective of this article is provide a new conversion algorithm on the basis of conversion from XML-GL to Xquery, it provide a new conversion method to lower the time complexity of algorithm, it improve the data query speed through combine new conversion algorithm and query algorithm. In this paper, the specific description of new conversion algorithm, algorithm flow have been show, in the support of improved conversion algorithm, users can do data query on the database platform, and improve the speed of query.After given new conversion algorithm, graphical inquires the conversion technology is applied to the college student management system of. To use graphical inquires the conversion technology to the student management system of the query scores query module are given through the experiment with the original conversion algorithm improved the conversion algorithm query results contrast.
