Design And Implementation Of The E-Card System Based On The Digital Campus

It is honor for the author to participate in the research and construction of E-card system of Xiamen University. And from it, the author deeply understood the details of the construction and application of E-Card in the Campus. The E-Card System is an important part and foundation of the digital construction of campus .Also it provides comprehensive data collection platform for the digital campus.Using the construction of E-Card system of Xiamen University as an example, this essay will illustrate design and implement of E-Card which include but not limited to the history and development of E-Card, digital campus, design principle of E-Card, function of E-Card ,platform construction of basic database, the topology of network, system security and the patulous application of E-Card system.At the beginning of essay, the author analyzes development of E-Card and the connection between E-Card system and digital campus. Simultaneously, the author analyzes the present situation for application of campus E-Card. In chapter II ,the author discusses how to construct a kind of managed E-card system by the object of construction, mode, principle and module of each function. Chapter III mainly introduces the design of key database which is also called basic database and implement of data-exchange between basic database and the units provided by it. Chapter IV mainly focus on the special character of Xiamen University's E-Card called rice-free-supply system whose application is an event of special significance.

In this chapter, the author labors the design of private network and VPN. As people always focus on the safety issue for E-card system, chapter VI set out the comprehensive implement of safety for E-card system by network of system, server, terminal unit, operating system, database system, date transmission and exchange, antivirus system. E-card system reflects the situation of study and Life Living for the teachers and students in campus. The system can provide a decision-making basis for the manager by graph after the work of data mining and analysis of all data. All the contents will demonstrate in the last chapter.
