数据库应用课程设计-线上美食订购数据库系统

一、项目简介

商家可以由食材供货源提供相应的食材，其中食材供货源有联系电话、负责人姓名、地址、供应商名称和供应商编号属性五个属性，其中供应商编号是唯一标识码，不同的食材供货源可以为不同的商家提供食材，并产生了提供量属性，商家有好评度、姓名、收入、账号和评价等级五个属性，其中账号是商家的唯一标识码。商家开设了线下餐厅和雇佣了外卖员，线下餐厅有餐厅号、餐厅好评度、外卖员编号和就餐人数四个属性，其中餐厅号是唯一标识码，外卖员编号是外键。外卖员有外卖员编号、联系方式、性别、外卖员好评度、外卖员编号和外卖员姓名，其中外卖员编号是唯一标识码。多个外卖员又隶属一个线下餐厅。
一个线下餐厅包括多个美食实体，美食有美食编号、价格、美食名称、销售量、餐厅号和美食好评度六个属性，其中美食编号是唯一标识码，餐厅号是外键。同一种美食通过销售可以产生多个销售额，销售额有销售编号、收入金额和美食编号三个属性，其中销售编号是唯一标识码，美食编号是外键。
不同的用户可以就餐多种不同的美食，产生了就餐时间属性，用户有用户账号、用户等级、姓名、地址和联系信息五个属性。一个用户包括一个钱包，钱包有用户账号、银行卡号、余额、优惠券和信任积分五个属性，其中用户账号是唯一标识码。多个不同的用户通过订外卖产生了多个不同的订单实体，并有订餐时间的属性，订单有订单号、用户地址、美食编号、数量、餐厅号、外卖员编号和总价七个属性，其中订单号是唯一标识码，用户账号、外卖员编号是外键。一个用户可以评论产生多个评论区实体，评论区有评论编号、订单号、美食编号、用户账号、餐厅好评度、餐厅号、评价等级、美食好评度和外卖员编号九个属性，其中订单号是唯一标识码，用户账号是外键。
多个不同的外卖员通过送外卖产生多个不同的订单实体，并产生了订单时间属性。

二、数据库概念设计

（1）商家实体具体属性如下图：

（2）线下餐厅实体具体属性如下图：

（3）外卖员实体具体属性如下图：

（4）美食实体具体属性如下图：

（5）用户实体具体属性如下图：

（6）订单实体具体属性如下图：

（7）评论区实体具体属性如下图：

（8）销售额实体的具体属性如下图：

（9）钱包实体的具体属性如下图：

（10）食材供货源的具体属性如下图：

系统基本功能的E-R图如下：
