Based On The Design And Implementation Of On-line Test System Of Random Unit Volume

In recent years,with the rapid development of Internet technology and computer technology,more and more attention has been paid to the wide application of new information technology in the field of teaching,and the online examination system supported by computer network technology has gradually become a hot research topic in the field of teaching.Under this background,the research and exploration of the corresponding intelligent online examination system for test paper grouping emerge in an endless stream.It is of great theoretical and practical significance to combine random set volume problem in online examination system with genetic algorithm and then apply it to random set volume strategy.This research is based on exploring how to deeply apply the online test system of random unit volume,studying the application premise of genetic algorithm,and taking improving the quality and speed of online test system as the research objective.In this regard,this study collected a large number of domestic and foreign research data,and according to the research results of the volume with the unit of the target,evaluation index,model,as well as the definition of genetic algorithm,advantages,application process were explored.Then,the paper studies the requirements of online test system based on random unit volume.The functional requirements are reflected in the requirements of question bank management,test paper bank management,and system management,and comprehensively discusses the functional requirements and non-functional requirements of the system through use cases.In the design of on-line examination system based on random unit volume,the basic framework and workflow are proposed,and the features and requirements of function realization are analyzed from three aspects of question bank management,examination paper bank management and system management,and then the database is designed.Finally,this paper implements and tests the online examination system based on random unit volume.The functional modules obtained from the system include question bank management module,test paper bank management module and system management module.The test results show that SQL Server2005 is used as the data management and storage support system of this system to optimize the online examination system based on random unit volume,and the functional modules it contains can also meet the needs of users,and then verify the scientific and reasonable genetic algorithm in the online examination system.At the same time,with the unit volume technology as the basis of the online examination system performance is good,has robustness,friendliness and other characteristics,therefore,the application of the system,will be in teaching,education and other aspects of a huge response,and then will be the majority of teachers and students support and acceptance.
