|
||
|
||
**三轮考试机制说明（2025-10-12更新）**：
|
||
- 一条考试记录包含三个轮次得分字段：`round1_score`、`round2_score`、`round3_score`
|
||
- 第一轮考试：创建exam记录，设置round1_score
|
||
- 第二轮考试：复用同一条exam记录，更新round2_score
|
||
- 第三轮考试：复用同一条exam记录，更新round3_score和score（最终得分）
|
||
- `score`字段用于兼容旧代码，通常存储最后完成的轮次得分
|
||
- 成绩报告优先使用`round1_score`作为主要展示数据

|
||
```
|
||
|
||
## 六、数据库设计原则
|
||
|
||
### 5.1 主键规范
|
||
- 所有表使用INT作为主键，满足当前规模与 ORM 定义
|
||
- 所有主键均设置为AUTO_INCREMENT
|
||
|
||
### 5.2 外键约束
|
||
- 所有外键关系都明确定义
|
||
- 删除策略：
|
||
- CASCADE：级联删除（用于强关联关系）
|
||
- SET NULL：置空（用于弱关联关系）
|
||
|
||
### 5.3 索引策略
|
||
- 所有外键字段自动创建索引
|
||
- 常用查询字段创建索引（如status, type等）
|
||
- 唯一约束字段自动创建唯一索引
|
||
|
||
### 5.4 字段命名规范
|
||
- 使用下划线命名法（snake_case）
|
||
- 布尔字段使用is_前缀
|
||
- 时间字段使用_at后缀
|
||
- JSON字段明确标注数据结构
|
||
|
||
### 5.5 软删除设计
|
||
- 使用is_deleted和deleted_at字段实现软删除
|
||
- 保留数据完整性，便于数据恢复
|
||
|
||
### 5.6 审计字段
|
||
- created_at：创建时间
|
||
- updated_at：更新时间
|
||
- created_by：创建人ID
|
||
- updated_by：更新人ID
|
||
|
||
### positions - 岗位表（2025-09-22新增）

|
||
```
|
||
|
||
## 六、性能优化建议
|
||
|
||
1. **分表策略**
|
||
- training_messages表可能增长较快，考虑按月分表
|
||
- exam_results表可考虑按年分表
|
||
|
||
2. **缓存策略**
|
||
- 用户信息使用Redis缓存
|
||
- 课程列表使用Redis缓存
|
||
- 热门题目使用Redis缓存
|
||
|
||
3. **查询优化**
|
||
- 使用分页查询避免大量数据加载
|
||
- 合理使用JOIN，避免N+1查询
|
||
- 统计类查询考虑使用物化视图
|
||
|
||
