手把手带你完成数据库课程设计（餐饮管理系统）
期末快到了，不知道各位小伙伴有没有在为自己的课程设计还没完成而发愁，不用担心，这篇文章将手把手带你完成一个餐饮管理系统。
1.顾客点餐部分
1.1界面部分
1.1收集顾客信息
这里收集到了顾客的电话和就餐人数信息后，会将对应信息收集到对应的数据表中
/**
* 起始页面,收取顾客联系电话和就餐人数信息并点击点餐后跳转CustomerOrderWindow页面
*/
public class CustomerIndex extends JFrame implements ActionListener {
Image image;
JPanel jp,jp_phone,jp_person;
JTextField jp_phone_jtf,jtf_person;

String phone;//传给点餐的那个页面
String number;

2.1.2后台管理主界面
后续代码就不做公布了，太长了
如果大家只需要应付课程设计的话，前面的顾客点餐部分就可以当作一个完整的点餐系统来完成课程设计要求了，并且已经有了完整的数据库设计的逻辑，足够大家自主学习了，源码现在已经开源到了gitee社区，链接地址如下：餐饮管理系统: 数据库课程设计——一个较为完整的餐饮管理系统 (gitee.com)
大家可以去这里下载源码，希望各位小伙伴觉得不错的话可以给我一个star。
希望对大家有所帮助。
