Aggregation is a specialized form of association that represents a "whole-part" relationship between the aggregate (whole) and a component part. In this scenario, a Rental Contract (the whole) logically aggregates Customer, Address, and Auto classes (the parts) because it encapsulates the details of the rental agreement, including information about the customer, the auto being rented, and the address related to the rental (e.g., billing or delivery address). This reflects a real-world relationship where a rental contract is made up of details about the customer, the car being rented, and relevant addresses.
