Application And Research On Data Warehouse And Middleware Technology In The State Administration Of Taxation

It is not easy for people facing to the "data sea" to make decision. The data warehouse technology is a good method to slove this hard problem,Now the data warehouse technology has become one of the focuses of database technology .Data warehouse technology can help user to process data,and find the intrinsic rule of the data, this technology also provide effective decision support. Middleware provides a flexible and independent data extraction and data centralized technology,which can realize the integration of the historical data and heterogeneous data.This paper focuses on the usages of data warehouse and middleware in the tax business,which can supply effective decision supporting.First,it introduces the data warehouse and middleware technology,and their their focus on the application and development of data integration.Second, by analyzing the distribution of data in the state administration of taxation, we bring forward the data centralized management system design goals.In this paper we discuss how to use data warehouse technology to establish center tax data warehouse and specify the logic model of the subject of tax sources analysis.Third,we focus on the application of middleware technology for the design and development of data exchange and data extraction module, and adequately demonstrated the function of data exchange and the work principle of data exchange and transmission.we also design the protocol of data exchange and transmission in order to realize the transparency of heterogeneous data transmission in different network topology,by the warehouse we achieve the organic integration of the data and solve the problem of isolation distribution of the tax data. Because of the use of middleware technologies the centralized data system has better applicability, flexibility,portability and scalability.By analyzing and designing ,we can see the technologies of data warehouse and middleware can play an import role in the tax data integration and tax decision analysis.
