摘 要

随着信息时代科技的飞速发展，计算机技术大大地提高了工作效率,在辅助教学中的应用也越来越广泛。智能背单词自测系统是一种高效、便捷的学习方式，具有直观性和趣味性，能够提高用户的学习积极性和主动性，从而提高学习效率。用户可以选择多种方式进行背单词自测，测试后系统能够立即批改，准确判断对错，并进行统计测试情况，最后显示正确答案。管理员可以增加、删除和修改习题，查看每个用户每次的使用情况并对其管理。

本系统采用目前流行的Java软件Eclipse 3.7设置界面，后台数据库使用MySQL Server 5.0设计，利用JDBC技术连接数据库，从而实现系统的基本功能。设计系统的过程中，首先建立了系统的结构框架，然后在此基础上进行数据库的设计，接着经过详细设计时的不断修改和完善，测试阶段的反复调试和验证，最终形成达到设计要求的可行性系统。

关键词：背单词；自测；Java；数据库

Abstract

With the rapid development of science and technology in the information age, computer technology has greatly improved the work efficiency, and it’s application in auxiliary teaching is becoming more and more widely. Smart self-test system is an efficient and convenient way for reciting words, it can improve the users' learning enthusiasm and initiative. So, the learning efficiency will be enhanced. Users can choose various ways to reciting words, the system can correct immediately after the test, and then carries on the statistical, finally show the correct answer. Administrators can add, delete, and modify exercises, view usage and manage users.

The system’s interface is designed by currently popular Java software Eclipse (version:3.7), the background database is designed by MySQL Server(version:5.0).

Using the JDBC technology to connect to the database , so as to realize the basic

functions of the system. First of all, establish the structure of system framework, and then design database on this basis, after the detailed designation, the system is

formed.
