Design And Implementation Student Online Examination System Based On Luo Ding Polytechnic

With the rapid development of computer network technology, evaluation examination based on network platform has become the development trend of modern assessment exams. The traditional computer evaluation examination system works mostly in C/S mode, although this mode of examination system has the advantages of stability and fast speed, it is too complicated for users to install and use. Online examination system based on B/S mode with openness and distribution features makes that modern evaluation examination breaks the limitation of time and space, and the objective and fair assessment scores of which have also been recognized by the examination staff. Therefore, the study of online examination system based on B/S has become an important task in many software development organizations or companies.Student online examination system of Luoding Polytechnic is a small online examination system which is based on the needs of Luoding Polytechnic examination process rule to develop. Development of the system is based on B/S three-tier structure and ASP.NET technology which is one of three major dynamic web development technology. VS.NET 2008 is the system development tool; backstage programming language uses C#. Through the analysis and research of several auto generating test paper algorithm, it determines that radio questions part of the online examination system uses backtracking auto generating test paper algorithm, the rest of the paper use randomly selected auto generating test paper algorithm. The combination of the two algorithms can greatly reduce the complexity of the algorithm, and also complete the automatic test functions. The system is designed by using URL modeling software to complete the system function modules. The System achieves the functions of professional management, paper management, test management, automatic marking management, student achievement query management, user management, system maintenance management and other key functions.The putting into use of student online examination system shows that the system’s basic function is consistent with demand functions. The system functions of requirements have achieved the desired objectives. System software testing and system security test shows that each tests of the system is in line good, and the safety and stability of the system is good. In addition, the system has expandability, security and easy maintenance features and so on. But with the continuous improvement of the intelligent online examination system, the function of the online exam system has to be further improved and enhanced, and to meet the needs of the modern examination and complete conveniently examination evaluation of every course.
