If a class contains the type of another class as an attribute, what is the relationship - association or aggregation?
eg.
A flight class containing the City class type as the Destination attribute - is it an association or an aggregation? What will be the name of their relationship anyway? Flying - "Arrival" -City?
Another scenario:
A FlightBooking class that contains the type of the BusinessClass class as an attribute, indicating that it is a group layout of a business class - is it a union or aggregation?
Thank!
A flight class with a type of City class as an attribute called Destination - is it an association or aggregation?
