【摘要】 传统的考试模式具有以下弊端:保密性差,人力、物力等资源大量浪费,考试反馈不及时,考试的公平合理性难以保证等诸多缺陷,并随着学生人数的增多,传统考试模式的弊端也更加突出。随着网络技术的发展,网上考试系统的应用可以很好的解决上述问题。本文根据新疆巴音学院教学改革项目“网络考试系统”为背景,设计并实现了针对巴音学院电子信息工程学院的网上考试系统。本文首先研究了网上考试系统的背景、现状和意义,然后针对开发网上考试系统中所所需的核心技术进行了详细讨论。研究了当前常用的C/S体系结构和B/S体系结构,对于.NET框架、ASP.NET、C#语言、SQL Server2005以及UML建模进行了简要介绍。本文采用UML建模方式完成了系统功能性需求分析,从安全可靠性、响应时间、可扩展性、可维护性、实用性和易操作性五个角度讨论了系统非功能性需求。采用模块化的思想完成了系统总体功能设计,同时完成了数据库概念模型设计和数据表物理模型。经过上述的技术研究、分析和设计,本文采用ASP.NET等技术设计并实现了在线考试、在线提问、成绩查询、用户管理、考试管理、提问管理、日志管理等功能模块。网上考试系统在设计实现的过程中,结合实际特色,从多个角度考虑师生需求。该系统的使用可以真正实现无纸化考试,加强考试管理,提高考试效率,及时反馈教学效果,降低了人力、物力的消耗,同时也提高了试卷评阅的公平公正性,使得考试更加真实可信,具有很好实际应用价值。更多还原

【Abstract】 In traditional style of examination, there exist shortcomings such as poor security, low efficiency, slow feedback, fragile fair and these become enlarged when confronting with the increasing amount of students.Along with the network technology is the Online Examination System that gives a perfect solution at the point. So based on the univer-sity of XinJiang Bayin’s project”Online Examination System”, the thesis manages to design and work out the Online Examination System for the department of electronic and information engineeringAt first, the thesis did evaluate the .NET framework, C/S and B/S architecture, and more expound some other basic supporting technologies such as programming language, development platform and the database. Then,the thesis approached the functional part of needs analysis through UML modeling; and the non-functional part in all the five as-pects of reliability, extensibility, maintainability, usability, and operability, and com-pleted the seperated modules and whole system design.At last, in all the functional tests, the implemented system showed its good performances.The Online Examination System, designed to meet the needs of teachers and stu-dents, can play a big role in morden no-paper test. Along with its good jod on the man-agement, efficiency and timely feedback, it is to show its worth in actual using.更多还原
