The other hand, also does not havea very good collection of information of importance to a large number of tax-relatedinformation, development, and utilization. So how does on tax collection andmanagement work in the form of a large number of tax-related analysis and utilizationof data, established on the basis of a scientific and strict and reasonable computeranalysis which model you choose, is to solve an important issue we face.This article seeks to proceed from the tax inspection work at this stage to the actualsituation, both at home and abroad through the tax inspection information status ofselected case studies and references, as a breakthrough in data warehousing and datamining technology, focused on data mining analysis method applied to tax inspection ofselected case. Made has by "case selection algorithm of tax check base on propertyexception detection ", on CTAIS(China Taxation Administration Information System，CTAIS) collection information system and other related involved tax informationsystem of large data for data analysis, extraction inspection selected case needsinformation of solution programme, and in accordance with tax inspection work pointunder of related provides, design out has inspection selected case managementinformation system, the system of development meet J2EE technology developmentspecification, system used B/S schema mode, easy system of maintenance and upgrade,System middleware used Weblogic8i, Back-end database use Oracle9i, select theWindows2003Server operating system, hardware platform, select Intel Pentium4Xeon2.8GHz, dual CPU processors, memory for8GB，Disk size for1TB server. Thesystem has a selection plan management, of unknown origin taxpayers list management,system data query, case inspection tracking feedback, summary report and the selectiondata into CTAIS and other functions, to fully meet the needs of the tax inspection work.It is worth mentioning that system provides the deal screening, case analysis module,deal screening module to realize the computer aided selection function, case analysismodule provides the taxpayers tax information, convenient to be checked taxpayer’ssituation analysis, greatly improving the audit personnel’s working efficiency。 This system have passed by the test of system software and hardware environment, testsshowed that the system with data cover a broad area, simple operation, suited topractical needs and so on. Use of the system, change the selected case of Shaanxinational taxation inspection working methods and technical means of the backwardsituation, improve the accuracy of inspection of selected case, is a highly efficient andaccurate inspection of selected secondary system, for the inspection of a selectedprovides accurate collateral, promoted the election of province inspection work whichby artificial means to information and scientific works.
