Defining Objects

An OBJECT is an abstraction of a person, place, thing, or concept within the problem domain that the information system must be aware of.

Defining Class

A CLASS is a template (specification, blueprint) for a collection of objects that share a common set of attributes and operations.

Objects

• Objects have three responsibilities:

*What they know about themselves – (e.g., Attributes)

*  What they do – (e.g., Operations)

*What they know about other objects – (e.g., Relationships)
