Duplicate check

With the automatic duplicate check, the address quality is checked and data management is made much easier. Duplicates are duplicate address data that differ minimally from one another. Such duplicates unnecessarily increase the amount of data and can lead to extra work when creating documents or even to documents being sent twice. This is where the automatic duplicate check comes in, as it detects and cleans up just such duplicates. This applies to all personal data - in both students and teachers data management.
