Design And Implementation Of A Provincial Tax Information Platform For Large Enterprises

Since the reform and opening up,after a long period of exploration and practice,our country has achieved the transformation from agricultural country to industrial country,forming a comprehensive,independent and complete industrial system now.At present,our country is to improve the quality and efficiency of industrial development,and strive to achieve the transformation from industrial countries to industrial power.In this process,China has emerged a large number of large enterprises,plays an important role in the national economy,is an important source of national revenue,taking Shaanxi Province as an example,more than half of the province's tax payable tax in 2016 large enterprises.Large enterprises,due to their diversified forms of organization and forms of operation,cross border,cross regional,cross industry and other characteristics,tax collection and management of the current tax departments have brought some challenges.In the information age,through the construction of information system for large enterprises,using Internet to achieve efficient information exchange and coordination office,is to solve the problem of asymmetric information in tax collection and management work of large enterprises,effective way to improve the tax collection and management of specialization and standardization.Based on the information construction of tax collection and management of large enterprises in Shaanxi Province,this thesis studies the design and implementation of tax information platform for large enterprises.The tax information platform for large enterprises in Shaanxi province is based on the existing tax collection and management information system,in view of the tax information platform for large enterprise management and the organization form of vertical development,through the tax data acquisition of large enterprises,realize the enterprise tax risk analysis and tax compliance management,guided by data,through the data analysis to discover and deal with the tax risk score and assessment of tax compliance,tax guarantee stability of large enterprises.In the demand analysis stage,this paper analyzes and describes the system requirements from two aspects of functional and nonfunctional,using UML case diagram modeling system in business function modeling,E-R graph model of the system is given;given in the form of the index of the performance of the system,the compatibility of the system nonfunctional requirements.In the system design phase,the overall design of the system is described from the system architecture,network architecture and functional architecture,and the database information table design of the tax information platform for large enterprises is described further.In the stage of detailed design and implementation,system selection J2 EE development environment,build the MVC development framework based on Struts2,introduces the design and Realization of 5 main function modules,each module in the introduction,the paper gives the function of program flow diagram,class diagram and sequence of Letu,the main function modules include: enterprise register management,data acquisition,risk management,compliance management and system management.In the enterprise register management,through the way of hierarchical management,the establishment of tree management system of large enterprises,large enterprises out of the internal organization and distribution structure;through the online submission and offline collection in two ways,the provincial administrative area within the enterprise tax collection and management of data integration and storage,to lay the foundation for data analysis.In the risk management module,based on indicators to achieve tax risk discovery,through the enterprise self-examination and risk response in two ways to deal with risk.Finally,the system establishes the taxpayer's tax compliance analysis through the sub scoring mechanism.In the test part of tax information platform for large enterprises,this paper using the black box testing method,5 function modules of the system in each unit testing,unit testing,test case was given,expected results and actual results,and show for the large enterprise tax information platform interface.Further,this thesis uses the stress test software to test the stress of the tax information platform to the large enterprises,and analyzes the system test results.The results of comprehensive unit testing and stress testing show that the design and implementation of the large enterprise tax information platform to meet the now large enterprises in Shaanxi province tax information management business needs,effectively solve the problem in tax collection and data analysis in the process of tax asymmetry of large enterprises,can improve the tax management specialization and refinement of the tax level and achieve the design goal.
