Design And Implementation Of Computer-Based Examination Management System Based On.NET

In recent years, with the development of computer technology, the traditional examination method is already cannot meet the needs of modern teaching. It is urgent for fair and accurate examination and can ensure test management system. It can improves the efficiency of the examination. Many schools have introduced computer system in teaching work. The computer and network technology are combined. The application is used in some teaching works, such as student management, examination management, administration management and other departments. In this way, the network examination also appeared, the examination questions are entered in the examination system server. It realizes the paperless examination. It isn’t timeconsuming in paper printing. The examination questions extract at random. The exam subjects content and order are different. The method puts an end to the exam cheating and plagiarism, it ensures the fairness in examinationThis paper introduces the design of a computer-based management system. It reduces the required manpower and material resources through the test system. It ensures the fairness and accuracy of the examination.The method reflects the level of students learning and teachers teaching, and can reduces the work pressure and intensity of teachers. Teachers can spend more time and energy to carry out scientific research in education. It improves teaching quality, promotes the development of the school.This paper analyzes the research background and significance of the computer management system, analyzes the present situation of the research on the examination at home and abroad. The functional and performance requirements of the system are obtained through investigation. According to the requirement of the system, the development technology of the system has been chosen, and the development of this system chooses C/S structure, which ensures the security of the system. The development framework of the system is.NET, the development tools is Framework.NET 4, the development language is C#. The system selects the Server SQL2008 database.The system analysis and designs from three parts, they are the test manager, test client and the console respectively. The roles of the system are test administrators,students and exam invigilators. The requirement analysis adopts the method of the use case diagram. At first, The system introduces the system design principle, then the overall function of the system is designed. The detailed design of the system are database and business process. Finally, the main interface of the system is realized inthe system. In this part,the software and hardware environment are introduced. After the system implement, the system need test. It includes function and performance test.The functional test is through use case, the performance test is through the software of Load Runner. After test, the function conforms to the expected target completely. The performance test is the response time when the number of user is different. The users operation are login test client and submitting operation. After test, the performances of the system are all meet the requirements.At present, the computer-based examination management system has been used,the use of the system reduces the manpower and material resources. It ensures the fairness and accuracy of examination, and can improves the quality of teaching. The users reflect that the effect is good, the performance is stable.
