python+mysql设计简单GUI的图书管理系统
图书管理系统:界面设计的比较丑请忽略数据要求根据系统的需求,将需要的数据分类记录如下:(1)图书信息:编号、名称、储量、作者、出版时间(2)图书借阅信息:读者学号、图书编号、记录编号、借书日期、还书日期(3)读者信息:学号、姓名、性别、班级、剩余最大借书量(4)管理者信息:管理者姓名、职工号、权限级别服务端:客户端:在这里插入图片描述import tkinter as tkimport tkint

图书管理系统:界面设计的比较丑请忽略
数据要求
根据系统的需求,将需要的数据分类记录如下:
(1) 图书信息:编号、名称、储量、作者、出版时间
(2) 图书借阅信息:读者学号、图书编号、记录编号、借书日期、还书日期
(3) 读者信息:学号、姓名、性别、班级、剩余最大借书量
(4) 管理者信息:管理者姓名、职工号、权限级别
在这里插入图片描述
