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。

一口气升级7个大模型SaaS应用，百度智能云：突出一个“开箱即用” - 2024/11/26
这一波大模型产业落地浪潮里，不少企业其实处在 “干瞪眼“的状态。
一种情况是，很多大模型产品看得见却摸不着，在台上一个个遥遥领先——今天Sora技精四座，明天英伟达的机器人又赢得满堂彩，可是到了台下一问：啥时候能用上啊？答曰：遥遥无期。
另一种情况是，企业想用上大模型，却又难免瞻前顾后——既要考虑场景融合，又得兼顾安全性，还要考虑打通现有系统，再加上各种部署成本和繁琐的采购流程……最后只能拂袖：罢了，再等等吧。

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
