Electronic Tax Declaration System Research and Implementation

Process shown in Figure 4,[link widoczny dla zalogowanych], divided into the Internet from the Internet to transfer into and out of. Internet relay server thereupon. l ▲ processing server within the network + l Figure 4, the data forwarding process deployment diagram Fig. 4Datasendingprogrammestructure order to meet future business needs change, and system design with separation of business and data messaging. The transmission of data messages is not specific data table structure and associated data tables and information and transfer all the specific requirements of the task configuration XML file, not directly write the code in the program. 4 Model for electronic reporting system based on tax returns and tax the first basic procedures for the determination shown in Figure 5 use case diagram. Figure 5 tax declaration process use case diagram Fig. 5Taxdeclartionprocedure package in this analysis is the main class of the boundary classes, control classes and entity classes. Boundary class includes tax authorized user interface, user interface, tax returns, reporting user interface, print,[link widoczny dla zalogowanych], user interface, to notify the user interface. Control class, including tax approved procedures, select the return process, fill out the return process, save the return program, fill in the paid tax program, send return procedures, tax prepayment program, the print process, notification procedures. Entity class, including tax approved form, return, taxes, receive notifications,[link widoczny dla zalogowanych], payment receipts. Draw the analysis class diagram shown in Figure 6. 4 Panhong Kun, et al: Electronic tax declaration system 369 * Research and implementation of notification procedures to notify the user to receive a single tax payment declaration of tax payment notice in Figure 6 to achieve the analysis class diagram Fig. 6Taxdeclarationanalysiscategryfigure electronic tax declaration system module is the core of the system. Taxpayers will have to declare the module is current output tax, the current VAT,[link widoczny dla zalogowanych], VAT at the beginning, the calculation of taxes and other projects and data, together with the taxpayer's registration number, name, bank account, etc. compiled into a report, send to the tax authorities. Whereby the tax authorities to determine the taxpayer's current tax liability. According to Figure 6, respectively, use case diagrams can be designed for individual use cases, to accept the taxpayer to complete online reporting, modify, review and send returns and other functions. Taxpayers report information is saved as XML files, report the same access is used in the treatment of: write to the database through XML files, but also through the XML file for reading. Review aspects of the declaration to take a different business based on business logic of the different special treatment, several steps common to the use of public class treatment. Among them, the key is to read XML file and write functions. Reading XML documents using SAX parsing algorithm mentioned above, write a list of XML documents is based on correspondence between the report generated automatically. Figure 7 for the reporting module of the processing flow chart. This module is divided into reporting options, report generation, report review, save and read the report. Function of each module can be converted for electronic tax declarations Servlet, the core of the reporting system functions. 5 Conclusion electronic tax filing system, method of using UML WEB-based tax return system is described. Starting from business requirements analysis, use case diagram describes the system from the user point of view function that the operator of each function, and conditions of use cases are described. Class diagram was constructed using the static model, taking classes related to the system. Flow chart was constructed using the dynamic model, control flow diagram as a tool for expression,[link widoczny dla zalogowanych], can be directly converted into Servlet implementation. Reporting module process flow chart in Figure 7 Fig. 7Processingflowoftaxdeclarationmodule tax electronic tax system in China after ten years of development, the system construction, software development, collection and management applications such as the depth and breadth, and gradually the application of the information made achievements, but will take from the management, technology and applications effort.
