But in the real There is a phenomenon of software construction lagging behind hardware, such as education managements assessment of candidates .Staying in the traditional exam mode is not only inefficient, but also has many disadvantages, causing the waste of information resources The actual operation of the system is good, and it not only greatly advances the informationization process of the test, but also makes it ,Schools will be more scientific, fair, impartial, efficient and networked. The network exam system should be able to satisfy a large number of examinees in any place, any time can take the exam, and automatically judge,Results. Through detailed analysis of the requirements of the test business, the main functions that the system should provide are as follows: (1) the test taker may take the test online, and the computer automatically judges the scores after the exam, and records the results.Candidates can also check the standard answers. If the exam time arrives, the system automatically prompts and stops the reply. (2) the instructor may establish and modify the library online, modify the personal data of the examinee, and monitor the examination situation. (3) the administrator may establish the examinee, the faculty and other archives on the Internet, and review the examination of the examinee to arrange the test for the examinee Candidates and the status of the test room, check the exam results, monitor the situation of the examination room and set up test items and exam questions.In addition, to ensure the fairness and fairness of the exam, the exam questions are extracted from the library by the computer. To put an end to strictly,The cheating behavior of the exam, after the system, should also provide fingerprints to verify the function of login. The main process is that the user sets the appropriate action according to the users permissions, depending on the users permission.The staff can modify the information of the examinee, modify the library, change the users password and monitor the examination,Conditions such as operation; After the administrator has logged in, the administrator will be able to review the library and set the test time, check, print test scores and so on. You can also set several terms: Test workstation: the client program that tests the test taker. It mainly provides random out of system configuration,Questions, verification login, test time prompts, automatic judgment scores, examination results, and standard answers. its In the implementation mode, the test workstation is divided into the client program and the web, which allows the candidate to pass the client programThe exam will be conducted in a way that allows candidates to pass the test site for the exam.Test application server: the application server of the network online examination system. It mainly implements data buffering and examination The encapsulation and reuse of the security patrols is the interface between the test workstation and the database server. The application server provides the abundanceRich interface. The business rules can be added or reduced by means of modules, given the upgrade of the test business
