C 语言教学网站及网上考试系统的设计与实现
摘 要：本文叙述了教学方式及考试方式的历史、现状、以及 ASP.NET 语言和 SQL
server2000 数据库管理系统的概况。重点介绍了 C 语言教学网站、网上考试系统和在线交
流模块的实现过程：包括系统分析、系统调查、数据流程分析、功能设计、数据库设计、
系统的运行环境、系统测试及调试。本系统主要面向两类人员使用：管理员（教师）、普
通学生，他们拥有不同的权限。考试模块使用的过程是管理员添加试题，制订出题规则，
生成试卷。学生登录后选择要考的试卷然后进入答题，完毕后提交试卷，存入数据库并评
分。系统管理员可以查询考生的成绩，每个考生只能查询自己的成绩。教学网站模块，管
理员添加教学文档，并对文档进行分类、修改等操作，而普通用户只能浏览内容。在线交
流模块中，任何用户都可以登录留言，管理员可以删除留言。另外总结了本系统的特点：
节约教学成本，提高考试工作的效率。

Design and implementation on the teaching web of C language and
examination system based on web
Abstract: This thesis narrated the teaching way and the test way history, the present situation, as
well as ASP.NET language and the SQL SEVER2000 database management system survey.
Introduced with emphasis on the C language teaching website, the net takes a test systematic and
the online exchange module realization process :Including system analysis, system investigation,
data flow analysis, functional design, database design, system movement environment, system
test and debugging. This system mainly faces two kind of personnel to use: The manager, the
ordinary student, they have the different jurisdiction. The test module use process is the manager
increases the test question, the making sets the topic of a composition the rule, the production
examination paper. The student registers the examination paper which the postselection needs to
test then to enter the answer, after finished submits the examination paper, stores the database
and grades. The system manager may inquire examinee's result, each examinee only can inquire
own result. The teaching website module, the manager increases the teaching documents, and
carries on operations and so on classification, revision to the documents, but the average
consumer only can glance over the content. In the online exchange module, any users all may
register the message, the manager may delete the message. Moreover summarized this system
characteristic: Saves the teaching cost, enhances the test work the efficiency.
Keywords: ASP.NET; SQL server; B/S; teaching web of C language; Examine system
