# 数据库详细设计
|
||||
|
||||
## 概述
|
||||
|
||||
本项目使用MySQL作为主要的关系型数据库，存储用户信息、牛只档案、交易记录、监管数据等核心业务数据。
|
||||
|
||||
## 数据库设计规范
|
||||
|
||||
1. 使用InnoDB存储引擎
|
||||
2. 字符集使用utf8mb4
|
||||
3. 所有表都有创建时间和更新时间字段
|
||||
4. 主键使用自增ID
|
||||
5. 外键约束用于保证数据一致性
|
||||
6. 表名使用复数形式，以下划线分隔单词
|
||||
7. 字段名使用下划线分隔单词
|
||||
8. 所有表都包含`created_at`和`updated_at`时间戳字段
|
||||
|
||||
## 核心数据表设计
|
||||
|
||||
### 1. 用户表 (users)
|
||||
存储系统用户信息，包括牧民、银行职员、保险员、政府监管人员等。
|
||||
|
||||
```sql
|
||||
CREATE TABLE users (
|
||||
id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY COMMENT '用户ID',
|
||||
username VARCHAR(50) NOT NULL UNIQUE COMMENT '用户名',
|
||||
email VARCHAR(100) UNIQUE COMMENT '邮箱',
|
||||
phone VARCHAR(20) UNIQUE COMMENT '手机号',
|
||||
password_hash VARCHAR(255) NOT NULL COMMENT '密码哈希值',
|
||||
real_name VARCHAR(50) COMMENT '真实姓名',
|
||||
avatar_url VARCHAR(255) COMMENT '头像URL',
|
||||
user_type ENUM('farmer', 'banker', 'insurer', 'government', 'trader', 'admin') NOT NULL COMMENT '用户类型',
|
||||
status TINYINT DEFAULT 1 COMMENT '状态: 1-正常, 0-禁用',
|
||||
last_login TIMESTAMP NULL COMMENT '最后登录时间',
|
||||
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
|
||||
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
|
||||
|
||||
INDEX idx_username (username),
|
||||
INDEX idx_email (email),
|
||||
INDEX idx_phone (phone),
|
||||
INDEX idx_user_type (user_type)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户表';
|
||||
```
|
||||
|
||||
### 2. 角色表 (roles)
|
||||
存储系统角色信息，如管理员、牧民、银行职员等。
|
||||
|
||||
```sql
|
||||
CREATE TABLE roles (
|
||||

|
||||
name VARCHAR(50) NOT NULL UNIQUE COMMENT '角色名称',
|
||||
description TEXT COMMENT '角色描述',
|
||||
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
|
||||
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间'
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='角色表';
|
||||
```
|
||||
|
||||
### 3. 用户角色关联表 (user_roles)
|
||||
存储用户和角色的多对多关系。
|
||||
|
||||
```sql
|
||||
CREATE TABLE user_roles (

|
||||
|
||||

|
||||
FOREIGN KEY (role_id) REFERENCES roles(id) ON DELETE CASCADE,
|
||||
UNIQUE KEY uk_user_role (user_id, role_id)
|
||||

|
||||
```
|
||||
|
||||
### 4. 权限表 (permissions)
|
||||

|
||||

# 数据库设计
|
||||
|
||||
## 概述
|
||||
|
||||
本项目使用MySQL作为主要的关系型数据库，存储用户信息、牛只档案、交易记录、监管数据等核心业务数据。
|
||||
|
||||
## 数据库设计规范

2. 字符集使用utf8mb4
|
||||
3. 所有表都有创建时间和更新时间字段
|
||||
4. 主键使用自增ID
|
||||
5. 外键约束用于保证数据一致性
|
||||
|
||||
## 核心数据表
|
||||
|
||||
### 1. 用户表 (users)
|
||||
存储系统用户信息，包括牧民、银行职员、保险员、政府监管人员等。
|
||||
|
||||
### 2. 角色表 (roles)

|
||||
|
||||
### 6. 繁殖记录表 (breeding_records)
|
||||

|
||||
|
||||
### 7. 交易记录表 (transactions)
|
||||
存储活牛交易记录。
|
||||
|
||||
### 8. 合同表 (contracts)
|
||||
存储交易合同信息。
|
||||
|
||||
### 9. 商品表 (products)
|
||||
存储牛肉商城商品信息。
|
||||
|
||||
### 10. 订单表 (orders)
