#### 分组创建流程
```mermaid
sequenceDiagram
participant Client as "客户端"
participant Service as "分组服务"
participant Logic as "分组逻辑"
participant DAO as "数据访问对象"
participant DB as "数据库"
Client->>Service : 调用GroupAdd
Service->>Logic : 转发创建请求
Logic->>DAO : 构建插入语句
DAO->>DB : 执行插入操作
DB-->>DAO : 返回插入ID
DAO-->>Logic : 返回结果
Logic-->>Service : 返回分组ID
Service-->>Client : 返回成功响应
Note over Client,DB : 分组创建成功
```

## 性能考虑
在设计分组管理功能时，充分考虑了性能优化。通过合理的数据库索引、事务管理和并发控制，确保系统在高负载下的稳定运行。

- **数据库索引**：在分组名称、创建用户ID和创建时间等字段上建立索引，提高查询效率
- **事务管理**：关键操作使用数据库事务，确保数据一致性
- **并发控制**：使用全局锁防止分组重复创建
- **批量操作**：支持批量添加和更新，减少数据库交互次数
- **缓存机制**：考虑引入缓存层，减少对数据库的直接访问

## 故障排除指南
在使用分组管理功能时，可能会遇到各种问题。以下是一些常见问题及其解决方案：
