### Create a Session Dependency { #create-a-session-dependency }

A **`Session`** is what stores the **objects in memory** and keeps track of any changes needed in the data, then it **uses the `engine`** to communicate with the database.

We will create a FastAPI **dependency** with `yield` that will provide a new `Session` for each request. This is what ensures that we use a single session per request. 🤓

### Eine Session-Abhängigkeit erstellen { #create-a-session-dependency }

Eine <abbr title="Sitzung">**`Session`**</abbr> speichert die **Objekte im Speicher** und verfolgt alle Änderungen, die an den Daten vorgenommen werden müssen, dann **verwendet sie die `engine`**, um mit der Datenbank zu kommunizieren.
