Based On Hybrid Model Of Online Examination System Design

At present various universities exam most used the traditional ways of examination, in the actual operation, the traditional test the way many disadvantages appeared gradually. Therefore, colleges and universities to a scientific, standardized management examination process,improve exam efficiency, improve the teaching quality and reduce the cost of exam, put an end to the work of the existence of the hidden trouble more urgent. With the rapid development of Internet network and popularization, can use the Internet network convenient, quick and other characteristics, and combining with the current college testing process is the actual situation, the online examination system design. The system can realize paperless examination, and can ensure maximum objectivity and impartiality of the exam.Based on the system function demand, based system function structure, database system model, and finally achieve the design development stage logon and identity authentication, extraction questions, submit statistical examination paper, the whole process of on-line exam score, etc. And to each process of scientific and effective comparison. Improve the efficiency of the exam, and greatly reduce the examination of the existence of the hidden trouble, as well as from a hand raise the student's quality of teaching.On-line examination system of a university network, according to actual situation of the construction of the system used by network structure from top to bottom, data management application layer points, network application layer and system layer. The system mainly use the campus internal LAN, and in Web server with a firewall and IP security package, VPN IDS (intrusion detection system), physical isolation system and anti-virus system multiple protective measures. To ensure the safety and reliability of the network.At the same time can will B/S and C/S hybrid system structure and the perfect combination of on-line examination system realization, effectively solve the traditional C/S structure in the campus network construction in the application of maintenance, B/S structure data security issues such as. Using C/S and B/S combination of scheme, and more convenient user. Using C/S structure can build fast data analysis process, statements, charts, and statistical results generated easy, complex logic realization and simple operation. Develop the more efficient and safe application system.
