Electronic Tax System Based On B / S Mode Design And Realization

In modern society, the rapid development of information technology, many advanced technologies apperd, the bandwidth of the network also increased, and the performance of the microcomputer doubled, which provide the necessary conditions for the rapid development of electronic tax. The most important part of the electronic tax network declare-not only improves the tax drawback of artificial, such as consume large amounts of manpower, etc, but also greatly improve the efficiency of the taxpayer.This article carries out a detailed requirement analysis, design, implementation and testing. Using ideas of MVC model and combined with software engineering theory, the system was designed and developped by adopted more popular technology system, JZEE. The main content of this study is below aspects:1. Some technologies used in analysis, design and implementation of system was introduced simply, including JZEE, database technology and information security technology etc.2.Requirement analysis for E-tax system was done, so that, functional requirements, performance requirements and security requirements could be acquired, based on which detailed description for each function module was done, and database design. In addition, some system securities and their solving strategies were discussed, and several possible solutions were presented. For example, safety Certification for users was designed and implemented in module of user log in order to effectively prevent unauthorized access to system.3.Based Four-layer architecture of J2EE, implementation for each function was done, including log module and Tax-declaration module.4. Adopted one kind of black box testing method based on interface, test for each system function was done to verify whether system requirements were meet or not.The realization of the system whcic based on J2EE has improved the level of electronic electronic, has played a very positive role in promoting the development of e-government.
