Design And Implementation Of Data Collection For Enterprises And Natural Persons

As the responsible unit for co-ordinating the national tax data,the State Administration of Taxation put forward to collect,analyze and utilize the national tax data centrally after the Golden Tax Phase III project was successfully launched nationwide.Therefore,the Golden Tax Phase III sub-project,namely Big Data Cloud platform project came into being.The continuous popularization and application of big data technology in all walks of life make the use of big data technology to solve the tax issue has become one of the important indicators of the modernization of taxation.The national tax data cover the source data of 70+online units of the country and the local tax,data exchanged between the external offices of the head offices and provincial offices,and open data obtained from Internet channels.Considering the characteristics of large amount of data,this dissertation completes the design and implementation of data collection system of enterprises and natural persons according to the actual demand of data collection proposed by State Administration of Taxation.Based on the idea of software engineering process,UML(Unified Modeling Language)is used as the descriptive language for system requirements analysis and design.The software development method based on RUP(Unified Process)and the tax proprietary cloud platform Framework,a comprehensive analysis,design and implementation of six subsystems of enterprise and natural data collection system.At present,the system has completed a series of data synchronization configuration file including output management,datax script call management,synchronization task execution management,code conversion management,data preprocessing management,data similarity calculation and management to MapReduce to achieve management,etc.functional module.After the use and testing of the tax-specific cloud platform development environment,it basically met the business requirements of the General Administration on the collection and achieved the pre-set goals,which effectively realized the efficient data of the enterprises and natural persons in 71 taxation agencies nationwide Accurately collected,and enhanced the availability of tax data for the subsequent application of tax data display provides high-quality data services.Because the data used in this study is tax data with obvious characteristics,the platform used is Ali's MAXCOMPUTE platform,and therefore it is only suitable for handling the tax-related requirements and has certain limitations.But still has strong availability in dealing with tax data.
