Research And Application Of Key Technique In Internet Tax E-filing System

With the rapid development of information technology and especially the application of Internet technology, the realization of taxation using IT and the exploitation of network e-filing system have become the trend of the times. The thesis designed and applied a web e-filing system of national tax based on the object-oriented idea and Hunan national tax network e-filing system. This thesis did some research work of key technique in e-filing system and applied it.This thesis investigated and ascertained the technology related to the system development based on the extensive research and thorough analysis of the status quo of net e-filing both at home and abroad. Research in Middle-ware and J2EE Platform,and resolved some key technological problems:1,The thesis analyzed the limitation of the traditional language ,gived a data model of e-filing and used XML to describe and save filing data. Furthermore the thesis made a detail analysis of two resolution models of XML file– DOM and SAX, and designed the resolution arithmetic using SAX model .2,We decided to using the MOM to transfer data because the inner and outer netwoks are isolated. The thesis put forward the JMS-based scheme and designed JMS-based sending and receiving arithmetic,and realized the data communication subsystem on the basis of the comparison of present common used information communication systems .3,The thesis analyzed and used the N-tier architecture and MVC design-pattern in order to improve efficiency and maintain ability of system, and give a system struture diagram of system struture of network e-filing system.On the end, this thesis started with the analysis of the demand and function of the net e-filing system,designed the database and environment according to the multilayer system structure and operation flow.,made the object-oriented analysis and design using UML modeling language and finished coding using Java programming language. Fully accomplished an Internet tax e-filingsystem based on Middle-ware and J2EE platform.The data from experimental unit indicate that the system is steady and reliable,reduces the time,increase the degree of satisfaction of taxpayer,validate the research production.
