Multi-Channel Tax Service Architecture Design And Key Technology Application

The process of informatization construction is changing the traditional mode of taxation administration information system, taxpayers oriented, taxpayer service available anytime and anywhere is becoming the important direction of tax information system. With the rise of tax informationization level, more tax service channel gradually improved taxpayers? experience. But overall, the quality of each channel level is uneven, channel construction goal is not specific, the difference of management level leads the taxpayer channel simplification of the actual optional, reduce the tax service level and quality.This system is based on the hunan land tax informatization construction situation, follow the principle of integration, using the advanced concept, technology, on the basis of the scientific process, classification, using J2 EE technology architecture and in the face of service specification, in accordance with the unified standard, function integration, coordinated operation requirements make tax payment service platform, to promote tax service work to provide more diversified and convenient channel for protection.This paper solves three key problems:(1) Using unified message and interface specification, as well as centralized data storage technology, solves the cooperation work between various tax channels, achieved consistency of logic and data of each channel business;(2) using the construction of CA authentication and key business interface system, ensuring the channel security access, realize safety, high concurrent invocations between core business system;(3) through the flexible financial statement data acquisition technology, solve the change table data caused by the problems of regular adjustment of financial data to be collected regularly, implement a custom configuration collecting various tax related data to various changes of tax forms without modify the program.This paper describes the background and significance of the research, then about the status of the tax service channel at home and abroad as well as existing problems of tax service channels in China, and introduces the main research content of this paper. The second part introduces the J2 EE theory and related technology research methods; The second part introduces the J2 EE theory and related technology research methods, from the business function, the unified tax system support and channel coordination of multi-channel has carried on the detailed engineering design;The third part of the system to realize the key aspects of:(1) support formula defined data acquisition model,(2) anti-denial of CA certification process,(3) implementation of high performance and high concurrency uniform interface service;The fourth part introduces the system development method and shows the system after the implementation of relevant interface, the system described in this article is being used in Hunan province land tax on-line more than 200 taxpayers and serving the entire province, finally summarizes the main work of this paper.Through this research, we realized multi-channel tax service system includes online tax, tax hall channel, self-service terminal channel and handheld tax channel. Through various channels and the united application supporting platform we realize the business cooperation system supports real-time and time limit business process. With business system integration and business tax sustainable maintenance, we achieved a fully functional system which has architecture unified and high performance.
