python实现外卖信息管理系统

本文为大家分享了python实现外卖信息管理系统的具体代码，供大家参考，具体内容如下

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

二、概念结构设计

系统整体的E-R模型：

三、逻辑结构设计

本系统所用到的表结构以及其联系：

1、店铺基本信息foodshop表

主键：shop_name

2、客服基本信息server表

主键：server_id

外键：shopname_shop_name

参考表：shopname 参考属性：shop_name

3、派送员基本信息courier表

主键：courier_id

外键：shopname_shop_name

参考表：shopname 参考属性：shop_name

4、学生基本信息student表

主键：student_phone

5、订单基本信息book表

主键：（student_phone，server_id）

外键：student_phone，参考表student，参考属性student_phone

外键：server_id，参考表server，参考属性server_id

6、配送基本信息delivery表

主键：（student_phone，courier_id）

外键：student_phone，参考表student，参考属性student_phone

外键：courier_id，参考表courier，参考属性courier_id

四、具体实现

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。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我们。
