The Tesearch And Realization Of Simulation System For Chongqing Computer Rank Exam Band One

The computer foundation education is the important part of an undergraduate's quality education. The class rate of the students major of non-computer, also become the valuation standard of all high school in education level and quality. ChongQing city university and college computer rank exam band one in 2001.So, For the sake to adopted the whole teaching system to the information and enumeral , we put forward the research and realization of simulation system for Chongqing computer rank exam band one .This essay from Chongqing education department, want to settle the request of the university students'quality education, strengthen students'social competition .for the sake of raising the computer foundation knowledge and the applied ability. here are so many grade examine systems, but the real system that match Chongqing's education outline and adopt to our students has not existed .Thinking the ex-test teaching and traditional mode that brings the problem and shortage, we put forward this system.The design of this system, set out from the actual need, we choose Windows Server 2000 as the network operation system, VB as the program language, Microsoft SQL Server 2000 as the database .According to the stability of the safety and system for examine, it takes C/S mode, the server is installed in a control room, the client is installed in other machines. Blend the network technique, the database technique and software frame technique.From Changing's situation and analysis, we give requirement and the system design, and introduced the software environment in detail: the operate system, the database system and the development terrace.Then introduced the database design, the response speed of system and safe technique of the database. The database design of this system follows the basic principle of the relation database, and to speed the response of system, we adopt to servers cluster technique.considerating the safety problem, we adopted a 3 DES entrapment technique, fire wall...etc. to guarantee a related information.The server part is divided into four basic functions: teachers and the students'management, grade management, database management and papers management; the client part is divided into two basic functions: Take examination and re-login. Start with the page and parts of codes that combine from the main function mold , we give out the main realization of the system.From the try running, we can conclude that this system strengthened a student to study actively. Then, we will perfect the system. the next step is to carry out the system completely for information and automation.
