Zibo Vocational Institute Online Examination System Design And Implementation

Along with the extensive use of network technology in education domain, the defects in prevenient manual tests are showing. It needs a revolution in examination method. And the examination relayed on network with advantages that the prevenient manual tests do not have is an advanced examination method. It is the prolonging of traditional examination hall and it can simplifies the course that the traditional examination was taken greatly if the data base technology is used effectively. Not only it can economize the mass manpower and the material resources, but also can raise efficiency and the quality of examination. And the Web technology examination system based on the aid of Internet can be operated very easily.Nowadays network examination is a better examination method. The examinee logs on by the full name, examination number or password, thus the examination thesis can come into being immediately according to content in item pool. And can adopt a large number of standardization examination questions, thus use the computer to judge rolling up, and raises the going over examination thesiss efficiency greatly; still can directly send the result to the data base to make operations such as adds up and sequencing etc. Therefore the network examination will be the trend of examination and develop network examination system with perfect function becomes an urgent desire. The thesis has done some study on network examination system, and has concentrated on the design and realization of network examination system.The thesis is summarized to the background of Network transfer mode , the current study situation of examination system, and Up-to-date development situation of relevant technology.The thesis takes the computer course C++ examination as an example and introduces the design process of developing the internet examination system and detailly introduced the design and realization of the major module in the system. The system development course fully uses object-oriented Analysis to analyses and designs, and concretely applies UML model picture to describe each stage of object-oriented software development. In the analyses of object-oriented requirement, uses case diagram to procures and describes requirement of users.According to Object-Oriented Analysis, this system is divided into examination, management for teachers and management for administrators three subsystems, and adopts the modularized developing method to develop. And ascend the questions recording in accordance with many system users, and made single sign-on users only need to ascend once can use between each subsystems, and avoided users many times ascending record between each subsystem, and also reduced code development capacity; then it concretely describe the function of random choose, automatic checking,automatic marking etc.The realization of this system lightens the teachers'burden, raises work efficiency, and meanwhile also raises the quality of teaching, making the examination more justice and objective, and arousing the study interest of students.
