1题目描述和分析
一个图形用户界面，有两种权限登录方式，分别是老师和学生。
老师登录系统能够查看学生的成绩以及一些基本的学生信息。如：学号，姓名，各科成绩。老师还能够在该系统里修改学生的成绩，登记学生的成绩。能按学号删除学生的记录，成绩等。
学生登录该系统只能够查看自己的成绩，不能修改自己的成绩。
该系统的登录都需要账号密码才能够修改和查看。在登录以前先选择好是老师登录还是学生登录，然后进入不同的页面行使不同的权限。
该系统需要与数据库连接才能够完成上述的功能。
2问题分解
3类的设计
本程序由于要用到图形用户界面所以用到了包有java.awt.*, java.awt.event.*, javax.swing.* 。 还连接了Microsoft SQL Server 所以还用到的包有连接数据库的包有 java.sql.Connection， java.sql.DriverManager，java.sql.ResultSet， java.sql.SQLException， java.sql.Statement。
类及其作用如下表：
SQL Server2008里有三张表：
4编码
见附录1.
5测试和发布
运行程序之后选择登录窗口：
选择老师登录与学生登录之后的页面：
老师登录之后的选择操作页面
学生登录之后的选择操作页面
添加操作
删除操作
修改操作
查询操作
6操作使用说明
首先运行程序进入主界面：主界面选择登录身份—老师，学生。
当选择老师登录输入在数据库中表teacher里的帐号密码之后进入老师的操作界面，在这个界面老师可以选择的操作有添加，删除，修改，查询等操作。这些操作只要输入正确的学生学号及在数据库chengjibiao里的学号，就能进行相应的操作。
当选择学生登录输入在数据库表student里的帐号密码之后进入学生的操作界面，在这个界面的学生只能进行查选操作，输入在数据库表chengjibiao里的正确学号就能查询相应的学号对应的信息。
7难点及关键技术分析
程序的难点是与数据库的连接上有点繁琐，在经过我在网上看到的很多资料之后把数据库与程序成功的连接了。
程序存在的不足是程序的界面还不美观，看着不漂亮。
8心得体会
通过这次课程设计我学会了使用Eclipse,还有Eclipse与Microsoft SQL Server 2008的连接。通过这次JAVA课程设计自己感觉自己的编程技巧有了一定的提高。
