设计要求
本课程设计，涉及输入输出、GUI设计、数据库操作等本课程重要概念和编程技能，全面巩固和加深学生对java程序设计的相关概念的理解，全面强化java编程技能，培养学生综合运用所学知识和技能分析问题和解决问题的能力。培养学生的团队精神和协作能力。
课程设计内容要求：
一、数据库设计：
创建库mydb（在mysql中进行）
数据表设计：
1． 学生通讯信息表
employee:no, name, sex, class, phone,email
二、功能设计：
- 功能模块选择菜单
- 用户登录
3．录入模块:
学生信息表按相应id录入。 - 数据的插入、修改、删除
三、界面设计：
1．用户登录
2．主窗体
四、设计要求：
- 采用GUI编程
2．画出功能模块图
3．Java GUI编程实现，要求： - 各功能模块功能清晰、单一。
- 各功能模块命名规范
- 界面友好
- 代码注释完整，准确。
一、功能介绍
该系统主要是用于管理学生基本通讯信息，主要功能包括两方面的：
1.管理学生信息，其中包括添加，删除，修改等操作。
2.查询信息，其中查询学生电话、邮件等信息。
二、设计过程
1.登录界面denglu.java
登录时，输入账号密码未填写、输入错误账号密码都会提出错误提示框。在填写正确账号和密码后，会提示正确并跳转到主窗体。
