     * Gets the super POM for the specified model version. The returned model is supposed to be read-only, i.e. if the
     * caller intends to make updates to the model the return value must be cloned before updating to ensure the
     * modifications don't affect future retrievals of the super POM.
     *
     * @param version The model version to retrieve the super POM for (e.g. "4.0.0"), must not be {@code null}.

* `Field(index=True)` 会告诉 SQLModel 应该为此列创建一个 **SQL 索引**，这样在读取按此列过滤的数据时，程序能在数据库中进行更快的查找。

    SQLModel 会知道声明为 `str` 的内容将是类型为 `TEXT` （或 `VARCHAR` ，具体取决于数据库）的 SQL 列。

### 创建引擎（Engine）

SQLModel 的引擎 `engine`（实际上它是一个 SQLAlchemy `engine` ）是用来与数据库**保持连接**的。

您只需构建**一个 `engine`**，来让您的所有代码连接到同一个数据库。
