The Application Of The Data Warehouse Technology In Taxation

The writing is based on an actual project, Beijing Fengtai Local Taxation Bureau comprehensive information management platform that developed by Beijing RongZe Limited Company.With the rapid progress in the building of information, a tremendous amount of data has been generated in taxation bureau. However, these data are place distributed, meaning differentiated, it is hard to turn these data into useful information. They need to be integrated, transformed, cleaned, extracted and loaded to data warehouse which help to change the data into 'knowledge nuggets'. How to make full use of these valuable data, which summed up the development of tax laws, tax administration and provide the basis for policy-making, tax information is a major issue facing the development process. Meanwhile, tax management tasks from extensive management to fine-management and the transition from management to deter coercive - type management, and we also need to use advanced analytical tools for managers and decision makers of applications to provide a unified system. And organizations need the suitable knowledge to operate their business. For that, building a data warehouse in taxation bureau can help to serve managers more conveniently to make up their decisions.The thesis did some research on how to build taxation data warehouse on the basis of being familiar to the taxation business and it's present information systems, we design the data model and the architecture of taxation data warehouse,give to the strategy of realizing concerning to data cleaning, integration, transformation and data load in data preprocessing. And study the logic&the physics of the data warehouse design , Further we build the taxation data warehouse. On the base of it ,we build the OLAP data base and OLAP cube ,and mine the data of data warehouse in a association rule mining system.So we can get the message ,that it is very useful for the leader to analysis and decisive ,and that instruct effectively revenue work.Through the technology of the application of Data Warehouse technology, and generalized analysis the processing interior and exterior data of the Taxation system,...
