Hello everybody!
I am currently studying for my exam and the teacher gave us the following sample exam. Unfortunately I do not have any answers of the correct solution and am not sure if I am doing it right or not. I would really appreciate if you could leave your opinion about it and tell me your opinion, of what the solution is.
It is about a data schema. Unfortunately I cannot upload more than one picture as a new member, but under this link you can find the questions :
Thank you very much in advance!!
