I want to create an ER-diagram from the following text for practise and I need some help with my diagram. If you look at my image, does it look correct to you or do I need to change something? I'm a little bit unsure about that registration part and about the arrows (Shall I have the registration as another entity with code as an attribute?!).
Can someone try to analyze this and give me some clues? I think I've almost completed the exercise but please take a look
