2、的一个子模块，主要功能是对学生的信息进行管理，如：插入一条学生的信息、删除学生信息、修改学生信息、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用例图图2.1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
