实战SSM_O2O商铺_02数据模型设计及实体类的创建

模块介绍

主要分为3个大模块

• 前端展示模块

---

• 店家模块

---

• 后台管理模块

---

建立o2o数据库（MySql）

---

数据模型及对象设计

总览

根据上述划分的功能模块，设计出主要的实体类（10个）以及实体类对应的表（10个）

下面来拆分逐个解析，创建实体类和库表

---

区域

分析

主要属性:

• areaId
• areaName
• priority (权重,数值越大页面展示越靠前)
• createTime
• lastEditTime

---

实体类

/src/main/java新建包com.artisan.o2o.entity，新建Area.java

##微信账号与本地账号

###分析

<font color=red size=4>这两个表与实体类的设计，**要通过外键用户ID与对应的用户建立联系** ，这样才能确定是哪个用户。
