 ### 3. 时间字段约定
 
-所有表中的 `createdate` 和 `modifydate` **必须由业务层生成并传入**，数据库Schema中**不设置** `DEFAULT CURRENT_TIMESTAMP`，也不使用触发器自动更新。
+所有表中的 `create_date` 和 `modify_date` **必须由业务层生成并传入**，数据库Schema中**不设置** `DEFAULT CURRENT_TIMESTAMP`，也不使用触发器自动更新。
 
 - 建表时：
   ```sql
-  createdate TIMESTAMP WITH TIME ZONE NOT NULL,
-  modifydate TIMESTAMP WITH TIME ZONE NOT NULL
+  create_date TIMESTAMP WITH TIME ZONE NOT NULL,
+  modify_date TIMESTAMP WITH TIME ZONE NOT NULL
   ```
 - Rust 代码中使用 `chrono::Utc::now()` 生成时间戳，统一在事务开始前创建 `let now = Utc::now();`，确保同一笔业务中各表时间一致。
-- `modifydate` 更新时同样需要在业务代码中显式传入 `Utc::now()`。
+- `modify_date` 更新时同样需要在业务代码中显式传入 `Utc::now()`。
