Based On The Theory Of Tax Data Warehouse Data Analysis Platform For Data Storage Study

With the development of taxation informationization, especially, system of stateadministration of taxation bureau has centralized all data on province level. Now dataanalysis become emphasis of high-class phase of informationization,. However, theproblems such as cross function, unshared data and disjointed supervision graduallyappear and the phenomenon of isolated island of information is more and more serious,which affect data analysis. Because of the lack of effective analysis means, it is difficultto offer comprehensive and exact data to decision-makers. Therefore, StateAdministration of Taxation has proposed the projcet of studying on taxation data analysisplatform in advance before the third phase of Golden Tax Project.On the basis of analysing current taxation application system and data analysis work,applying data warehouse theory and technology, this thesis studies the feasibility, methodsand steps of building data warehouse on taxation data analysis platform, designs the datamodel and structure of data storage, and mainly solves the difficulty on Operational DataStore (ODS), data Extract, Transform and Loading (ETL) and On-line AnalyticalProcessing (OLAP). Based on the study of the thesis, the uniform data storage structurecan be built, which can offer the standard and overall data source to data analysis,ratepaying evaluation and taxation prognostication.
