月摘 要

在网络技术逐渐渗入社会生活各个层面的今天，传统的考试方式也面临着变革，而考试管理则是网络技术一个很重要的发展方向。考试管理一方面可以突破时空的界限；另一方面考生在自己熟悉的环境中考试也会更自在，能更好地发挥自己的真实水平，网络考试方式将是以后考试发展的趋势。

本论文主要阐述了基于Web技术的C语言实验在线考试系统的设计与实现。论文首先对系统设计所涉及的相关技术进行逐一介绍，并主要对该系统的设计概要以及系统的设计方法及功能也作了详尽说明，系统按照软件工程的思想进行系统设计，在需求分析的基础进行功能模块划分，然后对各个模块进行分析和详细设计，并用相关技术实现。

系统采用B/S开发模式，以MyEclipse6.0作为开发平台，java语言为主要编程语言，结合JSP、JavaScript、Html、SQL等语言，以Tomcat为服务器和SQL Server 2005为后台数据库。最终开发一个拥有题库管理、组卷、判卷、信息管理的C语言实验在线考试系统。整个系统层次结构简单，操作容易，并具备一定的安全性。学生借助此系统，可以随时随地的进行考试，同时老师使用该系统能更高效、便捷的组织在线考试。

关键词：C语言实验在线考试系统，B/S开发模式，JSP

Abstract

In network technology gradually infiltrated into all levels of social life today, the traditional test method is also faced with changes, and examination management network technology is an important development direction. Examination management hand can break through the limit; on the other hand the candidates in the familiar environment examination will be more comfortable, can better play to their true level, network test will be the way of the future development of the examination.

This paper mainly discusses the Web technology based on examination management system design and implementation. First of all papers on the system design and the related techniques are introduced, and the system design and system design methods and functions are also introduced in detail, the system according to the thought of software engineering system design, needs analysis in the basic function modules, and each module was analyzed and detailed design, and use technology to achieve.

The system adopts B / S development mode, taking MyEclipse6.0 as the development platform, the Java language as the main programming language, combined with JSP, JavaScript, Html, SQL language, Tomcat server and SQL Server 2005 as the database. The eventual development of a question bank management, test paper, grading, the information management system of examination management. The whole system level has the advantages of simple structure, easy operation, and has a certain degree of safety. Students with this system, the test can be whenever and wherever possible, at the same time, the teacher use the system more efficient, convenient organization of online exam.

Key words: The experimental C language on-line test system, B / S development mode, JSP
