Based On Cross-platform Test System

Along with the development of information technology, many universities and colleges have already finished constructing campus network. But the use of campus network is still on the primary stage because of the conception of thinking highly of hardware and overlooking software. The exam system of spanning platform is simple in maintenance and convenient in service, and has been used practically in the fundamental teching of the computer.The system should be developed and realized management of examination questions and network examination according to the different special fields to accomplish the standardization, scientific and systemization as well in order to bring campus network into full play as soon as possible. The paper mainly inquires into something about network exam system of spanning platform.The paper focuses on studying the function of examination questions system in common use such as management of exam questions with network, automation, intelligention, popularization, as well as the functions of exam questions system such as producing exam questions, exam supervise and control, going over examination papers automatically, results management etc. in order to adapt the need of examination without papers.The paper aimes modern network examination system technology, and background a reform project in education of my college. This paper describes the process of the examination system on network based on J2EE model, introduces the requirement analyse, system design, design in detail, and other key technologies the system involved. In the end ,the paper also describes the Genetic Algorithm that is used in the auto-generating paper system, and does further research that using XML to display contents by different objects.The system is tried to practice in the teaching affairs office and get success, it can be exploited as its goal, and the use of this system shows the management develops into automation and in formalization. The control system will make the management high effect, normal and scientific.
