外卖信息管理系统（python+pymysql+wxpython+Mysql）

题目：外卖信息管理系统

一、需求分析
需求分析包含如下：
1、问题描述
以外卖信息系统管理员身份登陆该系统，实现对店铺信息、派送员信息、客服人员信息、订单信息、配送信息等进行有条件查询以及信息的录入、修改、删除等功能。

2、系统功能描述
（1）信息录入：使用wxpython设计排版编写窗口界面，给出录入信息的接口，通过python语句实现与数据库的连接，从而向数据库中插入相应数据。
（2）信息修改：使用wxpython设计排版编写窗口界面，给出修改信息的接口，通过python语句实现与数据库的连接，从而修改数据库中相应数据。
（3）信息查询：在窗口界面中，通过响应的按钮触发，实现与数据库的连接查询，得到所有在线店铺信息。
（4）数据统计：在数据库中编写相应的存储过程，输入店铺名称即可select其所管理的派送员和客服人员。

3、系统功能模块图

程序演示：
（1）店铺信息

（2）店铺上架

（3）店铺下架

（4）派送员信息

（5）订单信息

（6）买家订餐

（7）修改订单

查看订单信息确认已经修改

至此python借助pymysql操作Mysql数据库的增、删、改、查功能演示完毕，剩下功能不一一截图，原理类似。

五、总结
通过本次课程设计，我对本学期所学的“数据库”和python内容有了更深一层的理解和学习。对数据库的认识不再仅仅停留在课本的理论知识上，能够更加清楚的理解其后台的操作流程。对python的应用不再局限于编写简单小程序，而是做到了与数据库进行连接，通过wxpython前台窗口，对数据库传入相应的sql语句，从而实现数据库的插入、修改、增加、删除等操作，实现sql语句的前台明了化。在设计E-R图时，采用了Navicat for mysql这一针对mysql的可视化工具，使得表与表之间的关系得以清晰的呈现，这次课程设计使我获益匪浅，在巩固与拓展知识的同时，还学会了许多工具的使用，这对以后的开发提供了宝贵的经验和基石。
