Design And Implementation Of The Tax Source Management System

The current tax system, after nearly twenty years of construction, the informatization level has got rapid development, and achieved significant results. But the system focuses on the special business tax, information independent of each other,form the information isolated islands, failed to achieve the organic integration of variousinformation systems. The urgent need to a series of the organic integration of thebusiness system data, based on the data analysis, information system to promote thework of Taxation to the analysis results, to prevent the tax risk, improve work quality and efficiency.Through the analysis of the existing tax information system, based on data warehouse, multidimensional analysis, J2EE, WEB icon,workflow managementtechnology, the design of tax source management system and implementation are described. This article first carries on the analysis to the tax source managementoverall business needs, through the business use case analysis, to determine the system goals, the role of system boundary and system, and completes the functiondemand functions and modules of the system,the function description, DFD chart,module input, processing and output of each function module in detail description,and performance requirements, the system backup and security, system user documentation and other non functional requirements and system software, hardware,communication interface are discussed. Secondly, with the system architecture diagram, data flow diagram, object interaction diagrams of the outline design of the system architecture,system structure, performance, interface design and key modules. Then, by way of the flow diagram, sequence diagram, class diagram, the detailed design of the main function. The screenshots describing implementation filetax management system.The system mainly consists of workflow management, data analysis, early warning and monitoring, tax assessment, tax audit, accountability, joint management, assistant decision-making function. The comprehensive collection, anti forgery, data of production system through the introduction of the tax source management system ETL process, and through data analysis, monitoring, found that the risk of points, and then start the workflow, a series of tax assessment, on-site inspection, tax audit,accountability and other processes, effectively realize the information tube tax. The system also realizes the leadership decision-making through a multidimensional analysis, business intelligence. The system establishes the overall view of taxation information technology, the realization of the information measurement of risk management, information platform for tax scientific, fine management to establish a complete, efficient.
