Design And Implementation Of The Local Tax Data Comparison And Analysis System Based On J2EE

With the development of computer application, the national taxation, land taxation, as well as other government departments has accumulated a wealth of tax-or tax related data. It is identified as an area of future work to strengthen the collaboration between government departments so as to help taxation. Following the instructions in Advice on the collaboration between national and local taxation departments, a document issued by the state administration of taxation, taxation departments throughout the country are now computerizing their systems of data exchange and comparison.The Local Taxation Data Comparison and Analysis System makes possible information sharing between different regions, and combines data from the departments of local taxation, national taxation, traffic administration, as well as industry&commerce administration. The system implements data collection, transformation, classification, filtering, and eventually carries out comparisons and analysis according to the usage of the data. Then the system reports the results of comparisons and analysis to the tax authority to help prevent tax evasion.The thesis first analyzes the requirements of tax data comparison, and then goes on to describe the design and implementation of the taxation system in use, which is based on the J2EE technology and the warehouse paradigm. It uses the Sybase database and performs various tax data comparison. Later in the paper, I describe solutions to such functional requirements as data comparison, statistical analysis, topical analysis, data export, comparison with external data, and comparison with social insurance data. The paper is concluded with an outlook of the future development of the system.
