Design And Application Of An Report Forms System Based On XQuery

As a powerful measure of information organization and revelation, report forms are the important component part of the enterprise information system and advantaged tool of information browse, analysis and print. While there are some problems about the traditional report forms system more or less, such as singleness of report forms kinds, disunity of the format, be difficult to upgrade and maintenance the application program and so on. More and more enterprise wishes that there is a kind of report forms system which is based on high level query language. The appearance of the XQuery criterion makes it possible that design a resolve scheme based on criterion to implement query among totally different data sources. Therefore, the research in the report forms system based on the XQuery criterion becomes the technical hotspot.Based on the advantage of XQuery and the basic requirements of report forms system, a design of report forms system based on the XQuery criterion is conceived.There are a few meaningful attempts in this article on both designing and implementing:1. XQuery data model is made up of extensible XML information set, simple type value and some operations about them. The data model provides bottom data support and basic operation support to XQuery performance.2. This system uses extensible Qizx as XQuery implementing engine. It can collect data from all kinds of data sources to a XML file, implement data collection and interaction conveniently, and assure the real time of the collected data.3. In this article, there is a new report forms frame using report templates and XQuery. This frame can modify the report forms template easily but don't affect other parts of the application program. So, the system will have less maintenance problems and higher produce efficiency.This report forms system has been applied to the risk management system in which it performs the analysis of financing, statistic report forms, analysis of subjects and so on.
