Question

Bargain Bob's auto dealership sells vehicles. He sells Chrysler, Jeep, and Dodge brand vehicles. He tracks customer and manufacturer. Bob tracks only the main owner—all co-owners and co-signers are recorded elsewhere.
Based on the description above, what is the maximum cardinality between each instance of "Customer" and "Vehicle?"

Answer 1

Answer:

Customer(1) - (1) Vehicle.

Explanation:

Cardinality is the mapping of entities or group of entities to a cardinal value. It tries to show the relationship between two objects like a cups in a shelf or plates in racks.

The car dealer in the question, sells one car to a customer and keep or prioritise the record of the main owner of the acquired vehicle. So the maximum cardinality assignment of the customer and vehicle is one (1) to one (1) mapping.
