Object Orientation?

Translation

What is a model and why? o Simplification of reality. Abstraction of something for the purpose of understanding it. o In Software Engineering we use models to o n n n Understand how we communicate with the system Understand how various modules of system communicate with each other. To detect misunderstanding and miscommunications (A Picture is worth a thousand words)

Go Object Oriented o o Attach behavior and information to important objects. Associates relations between objects to describe static and dynamic organization and structure of real situation.

Object Oriented Modeling

Object o So an object is anything that n n n Has an Identity Has Properties And Behavior o Write down Properties (attributes) and Behaviors (Functions) of the guy in last diagram.

Relationships o Static n n o Relations exist over a long time. Objects know about each others existence Dynamic n n n When two object communicate with each other. Objects sending stimuli to each other. Stimuli = events, messages.
