基于JSP的开放式无纸化在线考试系统的设计与实现
摘 要
在二十一世纪的新时代，随着计算机技术的发展及计算机的日益普及，基于WEB开放式无纸化在线考试与无纸化办公一样已成为大势所趋。相比传统的考试方式，WEB的开放式无纸化在线考试系统的主要好处是一方面可以动态地管理各种考试信息，只要准备好足够大的题库，就可以按照要求自动生成各种试卷；另一方面，考试时间灵活， 可以在规定的时间段内的任意时间参加考试；另外计算机化的考试的最大特点是阅卷快，系统可以在考试结束时当场给出客观题考试成绩，计算机阅卷给了考生最大的公平感。
本论文讲述了一个基于WEB的开放式无纸化在线考试系统的大体实现过程，该系统基本上可以满足学校及现代信息化企业的内部考试要求，可以实现学校或企业的低成本投入，高效率办公的宗旨。例如：一个学校或公司如果使用了本系统，老师和领导即使在外地出差也可以通过访问Internet轻松设置审批考试`，考试结束后也不要传统的繁琐的阅卷过程，极大地提高了办公效率。考试的题型可以都是标准化客观题目，对于其他类型的题目只要在本文的基础上稍加修改即可。 关键词：开放式无纸化；在线考试系统；JSP；B/S模式
The Design and Implementation and Open Type Paperless
Online Examination System based on JSP
ABSTRACT
In the new era twenty-first century， along with the development of computer technology and the popularization of computer， online examination paper and open type paperless office based on JSP has become represent the general trend. Compared with the traditional test methods， the main advantage of the open WEB paperless online examination system is ， on the one hand， it can manage all kinds of test information， as long as the questions are big enough， it can automatically generate a variety of papers in accordance with the requirements; on the other hand， the examination time is flexible， can at any time in the specified period in the exam; the biggest characteristic in computerized exam marking system is fast， can be in the end of the exam was given objective test scores， computer marking brings students a sense of fairness.
This paper tells the story of a paperless online examination system based on open WEB in the implementation process， the system can basically meet the school and modern information technology examination requirements within the enterprise， can realize low cost school or business investment， efficient office purposes. For example: if a School or company using this system， teachers and leaders in the field trip can easily access the Internet through the examination and approval of the examination， after the end of the examination， not the traditional red marking process， greatly improve the efficiency of the office. The exam can be objective standard for other types of problems， as long as the topic in this paper on the basis of a little modification can be.
