## 导入与设置 `SQLAlchemy`

* 导入 `SQLAlchemy`
* 创建 `metadata` 对象
* 使用 `metadata` 对象创建 `notes` 表

```Python hl_lines="4  14  16-22"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

!!! tip "提示"

    注意，上例是都是纯 SQLAlchemy Core 代码。

    `databases` 还没有进行任何操作。

## 导入并设置 `databases`

* 导入 `databases`

{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Modify the OpenAPI schema

Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:

```Python hl_lines="22-24"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Cache the OpenAPI schema

You can use the property `.openapi_schema` as a "cache", to store your generated schema.
