Consider the EER model below and answer the questions, explaining how you got the answers from the diagram notation.

1. What are all the attributes of a Y?
2. What is the unique identifier of a W?
3. True or False: Whatever jumps over an F is either a Y or a Z.
4. Identify the multi-valued attribute in the diagram and explain what it tells us.
5. True or False: An R may be visited by something that does not jump over an F.
6. What are the minimum and maximum number of Y’s an R may be visited by?
