+### 4.2 数据流架构
+1. **前端请求流程**:

+2. **后端处理流程**:
+   - API路由 → 中间件验证 → 控制器处理 → 模型操作 → 数据库
+3. **响应返回流程**:
+   - 数据库结果 → 模型封装 → 控制器响应 → 前端状态更新 → UI渲染
+4. **实时数据流**:
+   - 设备数据采集 → 后端处理 → 数据库存储 → 前端轮询/推送更新
+
+## 5. 数据模型关系
+### 5.1 核心实体关系
+- **Farm (农场)** ← 一对多 → **Animal (动物)**
+- **Farm (农场)** ← 一对多 → **Device (设备)**
+- **Farm (农场)** ← 一对多 → **Alert (告警)**
+- **Device (设备)** ← 一对多 → **Alert (告警)**
+- **User (用户)** ← 多对多 → **Role (角色)** (通过UserRole中间表)
+- **User (用户)** ← 一对多 → **Order (订单)**
+- **Order (订单)** ← 一对多 → **OrderItem (订单项)**

+- **级联删除**: Farm删除时级联删除相关Animal、Device、Alert
+- **级联更新**: 主键更新时自动更新外键
+- **限制删除**: Product被OrderItem引用时限制删除

+# Farms静态数据导入总结
+
+## 概述
+成功将后端API中的farms静态数据导入到数据库的farms表中。
+
+## 数据来源
+
+### 1. API静态数据
+来源：`routes/farms.js` 中的 `/public` 路由
+- 宁夏农场1 (银川市)
+- 宁夏农场2 (石嘴山市) 
+- 宁夏农场3 (吴忠市)
+
+### 2. 种子数据
+来源：`seeds/20230102000000_farm_data.js` 和 `seeds/20230103000000_extended_data.js`
+- 阳光农场 (养猪场)
+- 绿野牧场 (养牛场)
+- 山谷羊场 (养羊场)
+- 蓝天养鸡场 (养鸡场)
+- 金山养鸭场 (养鸭场)
+- 银河渔场 (渔场)
+- 星空牧场 (综合养殖场)
+- 彩虹农庄 (有机农场)
+
+## 导入过程
+
+### 1. 创建导入脚本
+文件：`import-farms-static-data.js`
+- 合并API静态数据和种子数据
+- 使用事务确保数据一致性
+- 清空现有数据并重置自增ID
+- 批量插入新数据
+
+### 2. 执行导入
+```bash
+node import-farms-static-data.js
+```
+
+### 3. 验证导入结果
+文件：`verify-farms-import.js`
+- 数据完整性检查
+- ID序列连续性验证
+- 地理位置数据验证
+- 农场类型统计
+
+## 导入结果
+
+### 数据统计
+- **总计**：11个农场
+- **ID范围**：1-11（连续）
+- **数据完整性**：✅ 所有字段完整
+- **地理位置**：✅ 所有位置数据有效
+
+### 农场类型分布
+| 类型 | 数量 |
+|------|------|
+| 综合农场 | 3个 |
+| 养猪场 | 1个 |
+| 养牛场 | 1个 |
+| 养羊场 | 1个 |
+| 养鸡场 | 1个 |
+| 养鸭场 | 1个 |
+| 渔场 | 1个 |
+| 综合养殖场 | 1个 |
+| 有机农场 | 1个 |
+
+### API验证
+- `/api/farms/public` ✅ 返回正确的静态数据
+- `/api/farms` ✅ 返回完整的数据库数据
+
+## 数据结构
+
+每个农场记录包含以下字段：
+- `id`: 主键，自增
+- `name`: 农场名称
+- `type`: 农场类型
+- `location`: 地理位置（JSON格式，包含lat和lng）
+- `address`: 详细地址
+- `contact`: 联系人
+- `phone`: 联系电话
+- `status`: 状态（active/inactive/maintenance）
+- `created_at`: 创建时间
+- `updated_at`: 更新时间
+
+## 相关文件
+
+### 创建的文件
+- `import-farms-static-data.js` - 数据导入脚本
+- `verify-farms-import.js` - 数据验证脚本
+- `farms-data-import-summary.md` - 本总结文档
+
+### 涉及的现有文件
+- `routes/farms.js` - API路由定义
+- `models/Farm.js` - 数据模型定义
+- `controllers/farmController.js` - 控制器逻辑
+- `seeds/20230102000000_farm_data.js` - 种子数据
+- `seeds/20230103000000_extended_data.js` - 扩展种子数据
+
+## 注意事项
+
+1. **数据库连接警告**：执行过程中出现循环依赖警告，但不影响功能
+2. **事务安全**：使用数据库事务确保数据导入的原子性
+3. **ID重置**：导入前重置了自增ID，确保从1开始
+4. **数据覆盖**：导入过程会清空现有farms数据
+
+## 后续建议
+
+1. 定期备份farms数据
+2. 考虑添加数据迁移脚本
+3. 优化循环依赖问题
+4. 添加更多数据验证规则
+
+---
+
+**导入完成时间**：2025-08-21  
+**状态**：✅ 成功完成
