Design And Implementation Of Online Examination System For Safety In Production Based On ASP.NET

With the rapid development of computer technology and network technology, human society has entered a period of rapid development. It has become a form of education and indispensable method by using network in education activities. In recent years, online examination technology has got great development. It has a great advantage. Firstly, it realizes the paperless examination reduce. So, the system not only reduces the cost, but also meet the need of energy saving and environmental protection and the construction of a conservation minded society. Secondly, it also has the characteristics of fairness,accuracy and flexibility. Therefore, the online examination system has become one of the key research topic in education. It shows great vitality in modern education.Firstly, this paper analyzes the present situation of safety occupation training and examination in Xiamen. It discusses a series of problems existing in the traditional examination method. It also clarifies the research purpose and significance of online examination system for safety in production. Starting from the key key technology of online examination system,this paper introduces the technology of B/S architecture, C#language, Visual Studio2005and SQL Server database,which proves that the designing of online examination system for safety in production system is feasible in technology. On the base of the analysis of key problems and work flow in the online examination system,the paper determines the system’s functional requirements and non-functional requirements. In addition,the business flow diagrams and data flow diagrams are given in this part. In the part of the overall design, the physical and logical structure of the system are designed and planned. Network topology diagram and block diagram of the system are given. Three layer B/S structure is choosen as the logical architecture of the system. By means of database conceptual designing and E-R diagram analysising,detailed relation database tables are designed. In the detailed design and implementation parts,it mainly introduces the module of random sampling examination questions,online examination,question management,student information management,certificate management,statistical analysis and so on. Finally, this paper summarizes the design of the system.It points out the advantages and shortcomings of the system, some possible improvements and future works were presented.
