Automatic Performance Appraisal System Based On The State Tax Positions Under The Golden Tax Network Environment For Research And Development

At the beginning of the century, with the development of Golden Tax Project and electronic government affair, the four-order information net working for bureau of province, city, town and some of revenues has been built, and the business of revenues duty and some of administrative management is gradually management by computer. On the other hand, with the readjustment and development of tax administrative organs, the systems for role of duty corresponded with some applications software have been built, which creates an good environment for automatic examine of duty. However, some of software is brought or development according to its own business and satisfying the need of management at different stages, they become some data islands for different data technology. To realize the automatic examine using computer, the problem of transparent transformation of heterogeneous data need to solved at first, that is how to build an uniform platform for exchange data to realize the share of resource, with making the utmost of the existing resource.This paper through the programming design of the automatic examine system of duty for national tax system, based on the idea of embodiment the advantages of three-tier clienter/server, aiming at the key technology of server model based on .net frame used in the design and application of this system does some introducing for its application. The following three points are the emphases: (1) Using XML and SOAP as the media of heterogeneous data transformation and the remote communication protocol, respectively, and appling Web Service as the platform of disturbed application to realize the distributed hetergenuous transparent transformation; (2) Adoping the technology that combinig facing to service technology with the technology of smart client design, thread pool and Web Service asynchronism transfer commission to solve the problem of data trandfer for disturbed computation; (3) Apply some methods, such as purview setting based on part, security authorization mechanism and security configuration for DB, to enhances the system security in theenvironment of network.The real application shows that the operations of this system are steady, and the data transformation is accurate and fast. In the situation of two servers have the same job and 300 clienters run simultaneity, the longest delay is 40 seconds, and the data leak and system crash are never happened. During the time of eight months of testing run, it examines 5000 times, and produces approximately ten million records, which obtains higher efficiency of the administration.
