Home -> Community -> Usenet -> comp.databases.theory -> How to model properties?
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.
