2、学生信息、查询学生信息。本项目使用Java Swing技术，数据库采用SQLServer 2000,本项目的开发和测试都是在Windows平台下进行的，但由于Java的跨平台性，本系的移植性很强，也适用于其它主流的操作系统。本项目的开发工具是My Eclipse,连接数据库SQLServer2000来完成一个小的学生选修课管理系统中的学生信息管理模块。2用例图功能级用例描述添加学生信息描述项说明用例名称添加学生信息用例简述管理员添加学生的基本信息用例图前置条件管理员已成功登入后置条件学生信息被添加基本操作流程1输入“学生姓名”，“学生学号”，“学生年龄”，选择“学生性别”2点击“提交”按钮3

5、学生信息查询功能：能通过一个学生的学号来查询某一个学生，如下图图查询一个学生信息删除学生信息后的数据库的一个截图如下4.6：图4.6 数据库5数据库设计6源程序Student类/信管071郑胜楠2007021236package domain;public class Student /student类用五个实例变量来描述private Integer studentId;private Intege studentNo;private String studentName;private String studentSex;private int studentAge;/建立构造器, 因需s
