Research & Development Of Campus Card-through System

With the development of modern scientific technolony, Computer technology and communication technology and more widely applied in the campus. Presently, there are many problems in campus IC card system. It mainly behaves as follows: Firstly, with the rapid development of the application of card, every department of campus gradually sets up its own application system of card. But techniques and criterions introduced into these system of card are not harmony with each other. As. a result, various application system of card are not harmony with each other and resources can't be reasonably configured and shared; Next, each student has many cards, for example student certificate, the card for restaurants and telephone and so on. And these many cards are troublesome when they are used; Finally, because campus network was set up lately, the management of various departments of campus couldn't be identical with each other.With the IC card of radio frequency get gradually mature and each university campus net established and input using, it has offered technology guarantee for the establishment of campus one-card-through system, in campus, realizing one-card-through system has become the inevitable tendency of campus management development.The campus one-card-through system researched in this paper aims at the designation of a card to solve the problem that there are many certificate in campus and the management is too complex. The advanced radio frequency IC techniques and network communication techniques are used to realize the dream of using one card through campus which can surely bring many conveniences to students and teachers.Firstly, the paper makes an introduction of develop status, deficiency and its background of one-card-through. Secondly, expatiation is done on the system structure and function requirements of campus one-card-through system, followed by a description of the appropriate database suitable to campus one-card-through system; thirdly, the paper puts forward an overall plan of campus one-card-through system including the design of network architecture of the system, moreover, the paper studies a software research mode by combining Browser/Server and Client/Server. Fourthly, the paper explores the distributed database and the method of its establishment, the paper also attaches great importance to the key technology of distributed database, that is,the coherence, the parallel and security of database. Lastly, the paper makes a general description of the function of various application systems, illustrates concrete realization of management balance system and the management subsystem of computer-room and library management subsystem and Bank transfer accounts system.
