摘要

随着计算机的广泛应用，人们能够高效和方便快捷的处理许多问题，使其一些信息管理基本上完全的取代了传统的人工管理方法。随着计算机技术的发展，越来越多的行业实现了管理的信息化和自动化，教育行业也不例外。但在很多高校中四级考试信息管理作为学校管理工作中很重要的一个环节还没完全实现信息化管理。因此本系统选择学校的四级考试信息管理为研究对象，以实现四级考试网络化、信息化管理、提高工作效率、利于日后的统计工作，同时通过及时传递四级考试信息为目标。

本系统的目的是建立一个高效的四级考试平台，采用简洁高效的Java技术与MySQL数据库等技术，设计和开发了此四级考试系统。该系统主要实现了四级考试信息管理、查询管理等后台模块和前台模块四级考试模拟、查看等有机的结合起来，提高了管理效率。通过科学全面的测试，系统实现了上述多种功能。 本系统可以根据实际应用的具体情况，适当加以修改，以便更好应用。本系统操作简单，灵活性好，系统安全性高，运行稳定。

Abstract

With the wide application of computers, people can many problems efficiently and conveniently, so that some of its information management basically replaces the traditional manual management approach. With the development of computer technology, more and more industries realize the informatization and automation of management, education industry is no exception. But a link in many universities discipline competition management information as the school management is very important in information management has not fully achieved. Therefore the system choice of discipline competition information management of the school as the research object, in order to achieve academic competition network, information management, improve work efficiency, benefit the future statistical work, at the same time by passing the graduation thesis information in time for the target.

The purpose of this system is an efficient platform, using simple and efficient Java technology and MySQL database technology, design and development of this graduation thesis management system. This system mainly realizes the discipline competition information management, query management module and the module background discipline competition, the organic combination, improve the management efficiency. Through the science comprehensive test, the system realizes the functions.

This system can be used according to the actual circumstances, appropriate modifications, in order to better application. This system has the advantages of simple operation, good flexibility, the system safe, stable operation.
