Zusammenfassen:

Durch die Kombination von JSON-Dateien zum Speichern von Schülerinformationen und Kennwörtern für Lehrerkonten sowie zwei Ports, zwei Anmeldeports für Lehrer und Schüler, wird die herkömmliche Initialisierung unterbrochen und direkt in das System eingegeben. Außerdem verfügt es über eine Registrierungsfunktion, mit der sich mehrere Personen bequem anmelden können und verwalten.
