Design And Implementation Of Export Tax Rebate Monitoring And Management System

According to the need of macro-control on the industrial structure, China's export tax rebate policy has also done a corresponding adjustment, it is now exports under different circumstances for tax rebates, tax-free or tax. With the sustained growth of the export trade and the comprehensive implementation of management of export tax rebates early warning, the audit pressure of the tax rebate departments has been increasing larger and larger. However, existing business systems do not work effectively, thus affecting the efficiency of the work of the rebate departments, greatly increasing the workload of primary rebate sectors. Adopting the means of information to manage and control export tax rebates, can make import and export management departments strengthen tax rebate business convergence and prevent export tax fraud, further deepening the management of export tax rebates and the level of fine, improve work efficiency, reduce the burden of work.In response to this urgent need, we used the most popular J2EE as the development platform, with Oracle9i database, researched and developed the Export Tax Rebate Monitoring and Management System. As a auxiliary tool of the "Export Tax Rebate Audit System ", it mainly bases on the business data of the "Export Tax Rebate Audit System", together with part of business data of Integrated imposing and Management System. It can not only automatically filter export tax accrued information to provide basis for tax administrators, but also compute all of warning indicators for Rebate, select doubt export enterprises, arrange targeted assessments for tax rebates. This paper studied four Functional modules, including Tax Sources Surveillance, Early Warning Assessment, Tax Rebate Management and Statistical Inquiries. It is applicable to all levels of national tax departments, and has been comprehensively promoted in Shandong Province.The system is based on multi-layer model, which is widely used by senior management software, establishes Business exterior layer, interface layer, business logic and data access layer. The multi-database management architecture makes the system more advanced, reliability and scalability. Establishment of the interface isolation layer between business logic layer and Business exterior layer isolates user interface with a variety of business functions realization, which enable the system secure and easy to expand .With the Separation of the business logic layer and Data Access Layer, Data Access Layer provides data services for the business rules layer. And data from a variety of data sources can be achieved through data access layer.In summary, the main content of this paper and the contribution is:1) Use the method of the software engineering principle to analyze demand.2) Make use of modern tools such as J2EE technology to design System architectureIt designs the system overall under the premise of the full understanding and grasp of the needs of users, proposes the system operation architecture, and lays the foundation for coding.3) Using a variety of techniques, design and implement the system functions.In the process of the system, we fully consider all the possible scenarios to realize the needs of users in accordance with the business processes and the flow chart that is based on needs analysis of the users. Design and implementation of the Tax Monitoring function, can be used to strengthen tax rebate convergence and statistics to tax exports; Design and implementation of functional assessment, can be used to the statistics of the rebate pre-warning and assessment indicators; Design and implementation of the tax rebate management capabilities, supporting the rebate work that is urgent into electronic management; Design and implementation of statistical inquiry function, based on the data of "the export tax rebate system audit", according to the combination of different caliber inquiries; Design and Implementation of the system maintenance functions, to maintain the system indicators, parameters, user privileges.4) In addition, except the newly added data the system's data, is mainly from the existing "export rebates audit system", and a small portion of data is from the "comprehensive collection system". Therefore, we design the corresponding database.5) This paper also uses Black-box and White-box Testing methods for the four modules monitoring and management of export tax rebates surveillance, early warning assessment, management and statistical inquiries rebate, testing the robustness of the functional modules and functions, confirming the data-processing operations is correct.The System will further enrich the early warning indicators of the export tax rebate and related business, standardize and improve the tax assessment process, realize the third period of the Golden Tax Project and achieve the main business focus to the provincial system, and perfect the relocation, to adapt to the constant reform, standardized of the export tax rebate business, and the continuous refinement of management depth.
