Can an object's property have mulitple values? What is the difference between an object with a property with multiple values vs an object with a child with multiple children. What criterias can be used to determine which way it should be modeled? Are the friends of John a property of John or just relationships. How are properties of an object fundamentally different than relatioships with that object? In the diagram below "." represents a property. "->" represent a reference to an object.
->Mary
->Bill
