Design And Implementation Of Quality Audit Subsystem Of Data Management Tax Comprehensive Application Platform

Construction of data management tax comprehensive application platform is an important way to promote the development of tax information construction of Shaanxi tax bureau.Quality audit subsystem is an important part of data management tax comprehensive application platform.It is used to maintain,manage,modify the quality of data,to ensure tax data consistency,completeness,accuracy of the data management platform.At present,the domestic data management tax work does not reach the purpose of data integration of various business systems.Historical and decentralized business data cannot be effective integrate and utilize.In order to solve the problems of the current tax informatization,this paper designs and develops a data management system.First of all,this paper introduces the background of the system,explains the significance of system development,and then analyzes the status of related systems at home and abroad.And then this paper introduces and explains the related technology used in the system development process,including the use of the Hibernate framework and the Spring framework.This paper also conducts a demand analysis about this system.In the demand analysis of this system,this paper firstly makes a complete and overall analysis for the system.The context data flow diagram is used to define the boundary of the system.This paper makes system function analysis of each modules,and through the use case diagram,use case table,activity diagram,we make a detailed description of the demand.This paper makes a data model of the system.The entities in the system are obtained and the relationships between the entities are revealed by E-R graphs.After the system demand analysis,this paper describes the design and implementation of the system in detail.The architecture design of the system is described.A network structure of the system is designed,and a network structure diagram of the system is obtained.A system logic structure is designed and the logical structure diagram of the system is obtained.And an overall system architecture is designed.Then,the function of the whole system is decomposed,and the system is divided into many modules,which is convenient for the division and development of functions.The important system modules are described in detail,including the brief introduction of these modules.The static structure of the module is described by the class diagrams,and the dynamic structure of the module is described by the sequence diagrams,then the class diagrams and sequence diagrams are described.This paper also designs the physical structure of the database,the database table is described,and we describes the fields,the primary key and foreign key in the table.Finally,the system is tested and analyzed.In the testing phase,firstly,system test environment is introduced,and then functional test and non-functional test are carried out.Functional testing phase,the important modules were tested through the test cases.In the non-functional testing phase,the performance of the system is tested.After the test of the system,it shows that this system has satisfied the design requirements such as availability,efficiency and so on.Under the premise of national tax reform,in order to comply with the new requirements of social development,this system has been developed under the strategic arrangement of data management.The system for data management platform to ensure the comprehensive application of data quality,provide a guarantee for the implementation of the data management tax policy.
