The Army Online Examination Management System Design And Implementation

At present, the army has the characteristics of scattered stationed, remote. As a result, this makes the traditional way of training evaluation has been unable to keep up with the demands of the development of training 。 As the army informatization construction, we have had the condition to research the online examination system. Through the online examination system makes the training evaluation process is computerized, standardization, systematization and automation, change the way of learning and examination, strengthen the officers and soldiers training and learning effect.First, the thesis analyzed the research background, selected topic significance, the present research situation and research content of online examination system, Compared the advantages and disadvantages between the traditional and online exams, puts forward the necessity and urgency of the online exam.In the system development process, first has carried on the system requirements analysis, Through the analysis of the practical application demand research and technical requirements, understand the needs of users, By using UML modeling language for the online examination system modeling and gives the system use case diagrams, The combination of user requirements, design the structure of the system, and the detailed design of each functional module structure, and gives the flow chart of each function module.The development of the system implementation USES B/S mode, According to the functional division includes user login, question bank management, evaluation implementation, performance management and my assessment of several major functional modules, Among them, the inspection organization and examination of implementation is the core of the system module, Which implements the test paper generation, examination paper management, online exam and automatic marking and other functions. The group function is based on the genetic algorithm.Other functions module mainly realizes the result analysis and test question management. On the implementation, System development uses the ASP.NET technology, Microsoft SQL SERVER 2005 for background database, development platform using the Visual Studio 2008, development language is c # language. In terms of system security, according to the confidentiality requirements of special forces, provides the necessary safety design, to ensure the safe operation of the system.
