What is an object model ?

An object model graphically depicts the class the object belongs to, its associations with other objects, the attributes that make it unique and the operations that can be performed on it.

With reference to the example the components of an object model are:
	Class name. For example, the "thing" being modeled in the example falls into the general class of a complaint.
	Associations. A complaint is associated with an incident. This association is important because the incident triggers the complaint.
	Attributes. The information stored about a complaint is the name of the complainant, the date of the complaint and a description of the complaint.
	Operations. The operations that can be performed on a complaint are recording of the complaint details and resolving the complaint with the complainant.
