I am having trouble understanding how to work out the relationships between entities and their attributes, and how they are linked.
I understand the concepts of one-to-many, many-to-many, and one-to-one but i can't apply them!

Could somebody please explain to me how the solution is solved, and why it has to link to a certain attribute?
thanks

also could some ppl tell me some examples of metadata (info about data)?
