## Die App mit einem einzelnen Modell erstellen { #create-the-app-with-a-single-model }

Wir erstellen zuerst die einfachste erste Version der App mit einem einzigen **SQLModel**-Modell.

Später werden wir sie verbessern, indem wir unter der Haube **mehrere Modelle** verwenden, um Sicherheit und Vielseitigkeit zu erhöhen. 🤓

### Modelle erstellen { #create-models }

- Click the left sidebar "VCS Roots" here and create a VCS root [here](https://builds.gradle.org/admin/editProject.html?projectId=Gradle&cameFromUrl=%2Fproject.html%3FprojectId%3DGradle%26tab%3DprojectOverview%26branch_Gradle_Master_Check%3Dmaster)
  - Suppose the VCS root you just create is `MyNewVcsRoot`. Set "default branch" to `myTestBranch` where your code exists.
