Design And Implementation Of The Tax System For Construction And Installation Industryafter The Reform Replacing The Business Tax With Value-added Tax Based On SOA

After the reform to replace the business tax with a value-added tax,the tax patterns and processes have been changed.The old solution has been unable to adapt to the new situation in the construction and installation industry especially the foreign taxpayers.Therefore,it is necessary to design the risk index system and establish the corresponding information system.In 2017,the Nanning State Taxation Bureau innovated and constructed a tax management system for the construction and installation industry after the replace the business tax with a value-added tax.This information system based on the SOA and ESB architecture,to achieve data aggregation,statistical analysis,information exchange and other functions.The article expounds the complete solution.Includes requirements analysis,functional design,framework design,technical route,page design,database design,and system implementation.This paper solves the problem of interface integration between heterogeneous systems by using the SOA underlying architecture to achieve data exchange between business unit systems,through the integration of the ESB service bus,the data transmission,configuration of System data center routers,the transformation of format,the reduction of system coupling,and the reduction of system usage interface.Finally,this paper introduces the operation of the system and the results,and analyzes the possible further expansion and improvement in the future.The system has been on line in October 2017 without fault operation so far,and has been praised by the superior department.
