Obligatory MySQL/SQLite suggestion.

There was something about this before: Database
In the thread, Pete also explained how to create a database in Basic, and in which you can also delete records. It is more complicated than in MySQL. I wanted to try it, but could not bring myself to do it until now.
A very important point in a database is the simple deletion of data records that have become obsolete. Sorting is also important: by name and/or by personnel number, by entry date, etc.
