What is an exclusive subtype relationship? Give an example other than one shown in this book. Draw an IE Crow’s Foot E-R diagram for your example
Interview a friend or family member to elicit common examples of supertype/subtype relationships he or she may come into contact with at work. You will have to explain the meaning of this term to the person you are interviewing and provide a common example, such as PROPERTY: RESIDENTIAL, COMMERCIAL, or BONDS: CORPORATE, MUNICIPAL. Use the information the person provides to construct an EER diagram segment and present it to the person. Revise, if necessary, until it seems appropriate to you and your friend or family member.
