What functionality to add to the database?

Question

SQL

Non-standard question but already lacks ideas. I am writing a diploma "Design and development of a database for registration and accounting of purchases based on the Sports School of Martial Arts". I have already added everything that is possible (a journal, tables with buyers, an entrance, purchases, etc. ", but I need to add some more functionality. Maybe someone will advise, I don't need an implementation, just something that can really come in handy in this area and will be normal for a diploma description

Answer 1
