**FastAPI**不需要你使用SQL(关系型)数据库。

但是您可以使用任何您想要的关系型数据库。

在这里，让我们看一个使用着[SQLAlchemy](https://www.sqlalchemy.org/)的示例。

您可以很容易地将其调整为任何SQLAlchemy支持的数据库，如：

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server，等等其它数据库

在此示例中，我们将使用**SQLite**，因为它使用单个文件并且 在Python中具有集成支持。因此，您可以复制此示例并按原样来运行它。

稍后，对于您的产品级别的应用程序，您可能会要使用像**PostgreSQL**这样的数据库服务器。

### 小さなエラーは自動的に処理される

FastAPIでWeb APIを構築する際に、コードにエラーがある場合、FastAPIは通常、エラーを引き起こした単一のリクエストにエラーを含めます。🛡

クライアントはそのリクエストに対して**500 Internal Server Error**を受け取りますが、アプリケーションは完全にクラッシュするのではなく、次のリクエストのために動作を続けます。

### 重大なエラー - クラッシュ

しかしながら、**アプリケーション全体をクラッシュさせるようなコードを書いて**UvicornとPythonをクラッシュさせるようなケースもあるかもしれません。💥
