Python+tkinter+mysql实现简单的HR职位管理系统

一、数据表单设计

建立两张表，并录入数据：

hraccount表

hraccount表中数据初始化：

 job表

job表数据初始化：

二、代码设计

import tkinter as tk
import tkinter.messagebox
import pymysql
from tkinter import ttk

 三、运行测试

 职位管理界面

 职位变更界面

 如果HR和职位是一对多的关系呢，任取一个HR,可以管理多个职位，任取一个职位，只能被一个HR管理。这样的话，要在数据库表单多方(职位)设置外键为HRID。然后在程序设计中设置HRID为global变量，贯穿到整个程序的数据库增删查改(增加HRID条件)即可。这个需要实现的可以留言，未来更新。
