The Research And Design Of Campus One-card-through System

As the computer technology and network develop quiekly, information technology will bring the innovation of management lots of effect. The intelligent technology is applied on many situations. Presently, there are many problems in campus one-card-through 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 systems of card.But techniques and criterions introduced into these systems are not identical with each other.As a result, various application systems of card are not. Asiterions introduced into the systems are not identical with eachother. As a result,various application systems of card are not harmony with each other and resources can not 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 could not be identical with each other.Every university has set up its own campus networks,which makes it possible to establish campus one-card-through system;the gradually maturing of application system of radio frequency IC card provides the technique grarante for the establishment of campus one-card-through system. So the implementation of management of one-card-through in campus becomes an inexorable trend for the development of campus management.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 sued to realize the dream of using one card through campus which can surely bring many conveniences to strudents and teachers .Firstly,the paper makes an in introductin of develop status,deficiency an its background of one-card-system. 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;Thirdly,the paper puts forward an overall plan of campus one-card-through system including the choice of card, the storage of information in the card ,the design of network architecture of the system,moreover,the paper studies a software research mode by combining B/S and C/S.Fourthly,the paper explores the distributed database and the method of its establishement,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 functions of various application systems,illustrates concrete realization of Cardholder Management Subsystem and Accounts Management Subsystem.
