Hierzu zählen beispielsweise:

* E-Mail-Benachrichtigungen, die nach dem Ausführen einer Aktion gesendet werden:
    * Da die Verbindung zu einem E-Mail-Server und das Senden einer E-Mail in der Regel „langsam“ ist (einige Sekunden), können Sie die Response sofort zurücksenden und die E-Mail-Benachrichtigung im Hintergrund senden.
* Daten verarbeiten:

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.

!!! tip

They are generally all related to the same application.

The analogy in the relational database world would be a "database" (a specific database, not the database server).

The analogy in **MongoDB** would be a "collection".

In the code, a `Bucket` represents the main entrypoint of communication with the database.

This utility function will:

Es ist jedoch möglich, das anzupassen, ein bestimmtes CDN festzulegen oder die Dateien selbst bereitzustellen.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.

OAuth2 was designed so that the backend or API could be independent of the server that authenticates the user.

But in this case, the same **FastAPI** application will handle the API and the authentication.

So, let's review it from that simplified point of view:
