Research And Design Of Online Client-side System For Tax Declaration

With the rapid development of computer and network technology, and theimprovement of the taxation information construction, declaring tax online is anadvanced and well-rounded way, became a major trend of taxpayers chose. Thetaxpayer can used personal computer completed to declare tax through online in24hours on whole day, which can raised the work efficiency of the tax administration.Therefore, realize an online client-side system for tax declaration not only meets theurgent need for both the taxpayer and the tax administration, but also can provideconveniently, efficiently, and usability system for the taxpayer to declared the tax.This article analyzed the significance and background of the online client-sidesystem for tax declaration, and introduced the current situation of the system，pointedout the importance and necessary of the system realizing. On the basis of deeplyinvestigation for the business process and tax declaration information for theenterprise, the article determined the requirements of the system. And used theUnified Modeling Language and the use-case modeled the demand of the system. Thearticle introduced the detail design of the online client-side system for tax declarationfrom the system target, the system structure, the system runnable environment and thesystem database structure, and then explained the test content, method and result ofthe system and then described the realization process of the whole system. Lastly,conclude the whole study work in the article and look forward to the realization ofonline client-side system for tax declaration.Conclusively, the main characteristics of this system are as follows:1、Used modularity and componentized methods to developed the servicefunction of the system, implemented the encapsulation of functional logic andbusiness rules. The operation module was independent and different services areseparated. This kind of architecture has the characteristic of strong applicability,featuring independent service development and easy upgrade, and reduced relation ofthe operation module.2、The system could online upgrade, by the version automatic checked. When thesystem needed to upgrade, the system would automatically downloaded and installedthe patch.3、 On the frame designing, the system adopted the Client/Server mode, implemented the taxpayer submitted their data, completed the tax returns to thenational tax bureau in the system online, and the system also allowed the taxpayerrevoked their submitted data if it was wrong.
