The Design And Implementation Of The Component-Based Online Examination System

With computer technology and the rapid development of communication technology, traditional teaching methods also change occurred, distance education is under people's attention. Distance education for the students to learn the creation of a vast free environment, and provide a wealth of resources, extension of the space-time extension of the teaching dimension. But the vast majority of schools still use the examination courses way: Teachers artificial Test Paper, arrangements examination, examiners, the commentary changed papers, Tang points and statistics. Network Test System is the use of computer resources and network resources Test Paper, examination, score, analysis, the relative reduction of all sectors of the traditional examination of anthropogenic subjective factors, more rapid, objective, and to organize security examinations, and improve the efficiency of the examination and reliability, improving teaching effectiveness and the quality of teaching is of great significance.In this paper, the status analysis of the domestic and international study on the basis of the development of a proposed use. NET Component Technology and based on the three-tier Browser / Server model to design online examination system is more appropriate. In this way, all systems upgrades, updates are completed mainly in the server side, thereby reducing system upgrades, maintenance and updating of the workload; use. NET component technology can improve efficiency and reusability of the development, the flexibility to continuously improve the examination system functional.The main purpose of the study in this paper is used. NET Component Technology Design online examination system for the use of existing computer and network resources organizations paperless network examination, replace the traditional manual examination. How integrated components used for the object-oriented method and system requirements analysis, design and construction of system model, and systems and the difficulty of key technologies were studied. At the same time using database technology, ASP.NET, ADO.NET, and many other technologies, will be based on the three-tier system design for the B / S definitive online examination system.The significance of this paper is not only to achieve the success of a new structure, performance superior online examination system, but also in the design and development of systems used in a number of component technology and methods are highly versatile.
