Design And Implementation Of Network Examination System Based On B/S Structure

In view of the rapid development of computer technology and Internet technology in the past 20 years,the society has completely entered the era of electronic information.In the field of examinations,online examinations and training are becoming a new method and method of teaching evaluation.Various training platforms have mushroomed.Along with the constant development of electronic information platform,as well as communications,computer,media,the Internet and corporate Intranet digital ceaselessly,promote the paperless and the information of training activities,new training pattern in a rapidly changing,but also affects the people before training teaching habits,and in just a few years with the leap-forward development and progress.The online public security information online training system is based on B/S structure,and adopts the MVC three-layer architecture mode,using the Struts2 framework,JSP and Oracle database.The system enables users to be classified as administrators,teachers and students,respectively registering and logging in.Administrators perform system maintenance and database management.Teachers in the system can add the question bank,organize the examination,carry on the subjective question marking.Students use system login for the test.In this system the background can be custom test time,test goal management,the system use a lot of front desk page Jquery and CSS code,make public security information science online training system is both beautiful and convenient operation.The main features of this system include: first the different browser especially based on the mobile device browsers can ensure normal display.Second provision can enter the system time interval training,training takes time interval,conforms to the definition to complete training;The IP limit for training places and access to the training system can only be entered into the training system by users within the prescribed scope.Third through the table structure design and establishment of database model,MIDWARE,IDE and corresponding language selection,data operation class design implementation,the top page design implementation,the business layer design of key technical problems such as study,combining with the characteristics of the public security intelligence discipline knowledge and put forward feasible based on the research of network public security intelligence online training system and the design idea,improve the quality and efficiency of the public security intelligence training system.
