C语言试题库管理系统的设计与实现

XX, 数学计算机科学学院

摘 要：“C语言程序设计”课程是很多高校大部分学生的一门必修课。由于课

程的特殊性，需要大量的习题资源来帮助学习。然而由于学生本身的经济能力及一些资料上的题型无法及时更新，并不能满足学生的要求。另外采用传统的人工出卷会花费老师大量的时间，物力和精力。因此如何既能满足学生要求又能为老师提供便捷成了重要的课题。这时候C语言试题库管理系统就被提出来了。 本文首先介绍了题库建设的现状和开发工具，然后提出了C语言试题库管理系统的需求分析，明确了系统的总体结构。并论述了利用JAVA、数据库技术，设计与实现基于C/S结构的C语言试题库管理系统的全过程。主要解决了试题库的建立、试卷生成、系统的安全性问题。本文详细论述了系统总体设计思想、数据库设计以及功能模块设计等。从而实现C语言试题库管理的信息化，规范化和试卷生成的自动化，并使其操作简单、方便、快捷。

Design and Implementation of the C Language Test Library

Management System

Chen Wei，School of Mathematics and Computer Science

Abstract：\program design\is a compulsory course for most students

in many universities. Because of the particularity,students need a lot of exercise resources to help learning. However, because the student own economic ability and some data types cannot be updated in a timely manner, it can not meet the demand of students. In addition to adopt the traditional manual volume takes the teacher a lot of time, material and energy.So how can meet the students' requirement and can provide convenient became an important topic for the teacher. At this time,C language test library management system was put forward.

This paper introduces the present situation of the construction of the test and development tools, and then puts forward the C language test library management system of requirement analysis, the general structure of the system. And discusses the process which use JAVA, database technology, design and realization based on C/S structure of C language test library management system. This paper mainly solves such …… 此处隐藏：5823字，全部文档内容请下载后查看。喜欢就下载吧 ……
