Modeling generalization and Customer generalization
Begin with a problem statement that describes customers
Identify the properties of customer from the problem statement
Place all properties into a class definition
Select a subclass for each value of the discriminator
Create a subclass to the superclass with a generalization association
Identify the properties that are not common to all types of customers.
Move the unique properties down to the subclasses that they describe.
Please note that this example used only attributes. However, the process includes distribution of operations and methods (operation implementations) as well. This too will be covered in the design part of this series.
