I'm creating a survey for visitors of my event. However it's been a while since I created a database. So I need some help.
I found some solutions but they are way too extensive and that is something I don't need.
Visitors need to stay anonymous but they can leave their email behind (seperate table
Emailsthat isn't linked to anything atm).
They have about 20 questions, some are open, some are one option(radio) and some are multiple options (checkboxes).
The questions need to be reusable.
That's about it. I just don't know how to go beyond the many-to-many in the diagram.
