Give an example (other than those described in Chapter 2 or lecture notes) of each of the three types of relationship degrees. Express each relationship with an E-R diagram. No need to include any attributes. However, for the unary and binary relationships, you need to denote the relationship cardinality and clearly state the corresponding business rules. For the ternary relationship, you need to state how the three entity types participate in the relationship and explain why it is not the same as three binary relationships.
