Design And Implementation Of The Risk Management Module In The Tax Comprehensive Management System

In the information age,the rapid development of the social economy has led to the continuous reform of the tax system and the rapid development of science and technology has also promoted the management of the tax authority of the information process.In the national tax reform conference held in July 2012,the State Administration of Taxation put forward to risk management.The risk management is a process about tax collection and management,form risk recognition,rank,evaluation to risk management,which is in order to implement the risk management strategies of alienation and progressive,and further deepen the tax professional management reform.In this background,this thesis studies the design and implementation of tax risk management module in the comprehensive tax platform.According to the basic principle of tax risk management,the establishment of data acquisition,data conditioning system,establishment of taxation data warehouse using the first,second and third party tax related data,through the tax risk index and the index model recognition may exist the risk of tax,the establishment of tax risk source database,and then through the key indicators of value,average value and the critical value for the weight of risk rank,according to the risk classification,classification pushed to different departments to deal with for risk response.Ultimately achieve recognition,evade and reply the risk of tax evasion,to protect local fiscal revenue,maintain the state's tax revenue.On the demand analysis stage,the to the domestic and foreign existing tax risk management information system functional analysis,constructs conforms to the tax risk management information system needs the function module,in the description of the specific needs of,this paper based on the UML use case diagram of the system of business were describing,from the realistic demand of gives the system demand performance indicators and data security protection strategy.Data quality is the foundation and life of risk analysis.In order to guarantee the quality of data,the data quality must be modeled and stored scientifically,which meets the requirement of data calculation and analysis.In data modeling,this paper uses E-R diagram model to model the entities and relationships involved in the risk management of tax and fee,and gives the design of the relational data model and information table.In the overall structure of the system,from three aspects is discussed in this paper,we first give the B/S structure of the network topology architecture design;from the perspective of software architecture,the software architecture design based on the workflow,process management to achieve the standardization and scientific process of risk response through.Finally,from a functional constitute angle,and function of the system is given in this paper.Some of the business system design and implementation.In this paper,the J2EE development platform,based on Ajax technology of system development,using Oracle as the background data.In this paper,the first class diagram design of the whole system,then based on the flow diagram and the sequence diagram gives details of design and implementation of the specific function,in the tax risk management,the major business functions including risk planning,risk identification,risk ranking and push and risk response.Finally,the system is verified through system test,including function test and performance test.In functional testing,the black box testing method is used.According to unit testing and integration testing,system functions are verified.Performance test includes system response time,stable and recovery ability.In addition,we also test the system through pressure test software.Test results show that the tax risk management system can meet the needs of the risk management and achieve the goal of the system construction.
