Based On The Tier C / S Mode, The Status Of Major Commodities Digital Identification System Research And Development

Traditional two layers Client/Server structure generally put company regulation of application system into client program of application. If company regulation changes, client application will change too. And if clients read and write data too much at the same time, it is easy to generate network congestion and low efficiency. The best solution to these problems is to use three layers Client/Server structure to develop application.The paper mainly focuses on research and development of zhong-da Merchandise Identity Digital Recognition System. After researching and analyzing current situation and tendency of electronic government work software and company logistics software, the system development pattern of whole commodity pursuit function and integrated inspection and confirmation function and internal company logistics management function is indicated. The system is important to improve government work efficiency and regulate company logistics management.The method to do research in the article combines theory technology and theory model with application. Firstly, COM technology is introduced. Second, the platform design of system is presented, and application of three layers client/server structure is demonstrated. Third, as the instance, the application of zhong-da Merchandise Identity Digital Recognition System is explained. Additionally, the critical technology of system is analyzed and introduced profoundly. At last, it summarizes the research the author dose, and analyzes the existing problems of system and further developing functions.
