The Design And Implementation Of Internet Tax Survey System Based On XML

The article employs the advanced XML and Java technique to design and realizea new type of tax network survey system, according to the present operation need inthe tax survey system of our country. The new system integrates the B/S system and C/S system, namely, using theB/S system to gather data and using the C/S system to analyze data, in order to reducethe cost of tax department and taxpaying company and improve the work efficiency,and makes best use of the advantage of Internet to complete effectively the task ofdata gathering and delivery in the tax survey.The new system designs the FORM describing language which based on XML asthe describing language of the tax survey table by using the characteristic ofself-describing of XML, to fit for the fast changing of tax survey table parameter andthe complicated logic as well, and then constructs the fountainhead code of JavaApplet by the FML resolving procedure. The design has realized the separation of thesurvey table describing and showing, and improved the developing efficiency for userinterface and maintenance ability. Because in the multifarious taxing job people oftenuse the table delivering in most time, while it is the tax job need that the table modeand table logical relation should change frequently, so it is suited especially in thetechnique to use the describing language for completing the tax job.For the XML database technique is still immature and, the tax survey data basedon XML coding which achieved from browser is needed to be transformed to relationdata, the transform arithmetic based on mapping is used in this article.In order to write the XML data into the server by Java Applet, the author designsa JSP process in the server so that this process will keep the XML data in the disk ofserver as proxy server does, and the process is named as server-proxy.Due to the consideration of expansibility and security, the new system is dividedinto two parts of inside net and outside net according to the tax survey operation flow.
