Abstract 学生选课及信息管理系统的设计与实现 II 1 摘要 学生选课及信息管理系统的设计与实现 摘 要 随着科学技术的日趋发展,计算机已经在人们生活的各个领域中都起到了越来越重要的作用．作为计算机应用的一个重要部分，计算机信息管理也被广泛应用．相比手工管理，计算机管理有着很多无法比拟的优点， 例如：查找方便、可靠性高、存储量大、必威体育官网网址性好、寿命长、成本低等．学生选课系统作为学校管理中不可缺少的一部分，对于学生管理者来说至关重要，所以系统应该为用户提供充分的信息管理和方便的查询手段．但一直以来，人们使用人工的方式管理文件档案，这种管理方式存在着许多缺点：效率低，必威体育官网网址性差，另外时间一长，将产生大量的文件和数据，这对于查找、更新和维护都带来了不少困难．因此，学生管理系统应运而生．使用计算机系统来管理学生的选课信息，可以极大的提高学生管理的效率，同时也为学生管理带来方便． 本系统使用JAVA语言来开发制作界面，使用SQL SERVER 2005做后台数据库支持．这使得系统有较高的安全性和较好的性能．根据登录类型的不同，系统登录以后弹出不同的窗口：学生窗口和老师窗口．学生在系统中可以选课、退选课程、修改密码．教师在系统中可以现实以下功能：学生的增加，删除，修改，查询；课程的增加，删除，修改，查询等功能． 关键词：毕业论文；选课系统；JAVA；SQL server Abstract With the increasing development of science and technology, the computer has been in all areas of people’s life and it has played an increasingly important role. As an important part of computer applications, information management is also widely used. Compared to manual management, computer management has many incomparable advantages, such as: easy to find, high reliability, large memory capacity, security, long life and low cost. Students’ elective system as an integral part of management, is crucial for students to managers, so the system should provide users with adequate information management and convenience of the inquiry method. But people use manual management of paper files, the management approach, there are many disadvantages: low efficiency, poor security, the other over time, which will have a large number of documents and data, making the search, update and maintain all with a lot of difficulties. Therefore, the student management system came into being. Using a computer system to manage student enrollment information, can greatly improve the efficiency of student management, the system is also for student convenience. The system use the JAVA to create interfaces, and SQL SERVER 2005 was used to do back-end database support. This allows the system has high security and better performance. According to the different log types, the system after logging in will sho
