Abstraction
Different forms
Different levels of abstraction
Various purposes
Levels of Abstraction
Guides to the thought process Abstract specifications of the essential
structure of a system Full specifications of a final system Exemplars of typical or final systems Complete or partial description of
systems

A Brief Summary
General-purpose visual modeling language for discrete system
Captures information about the static structure and dynamic behavior of a system
Contains organizational constructs for arranging models into packages
NOT primarily a programming language

UML Views
4 AreasStructural classificationDynamic behaviorPhysical layoutModel Management
UML Views
A subset of UML modeling constructs
Represents one aspect of a system
One or two kinds of diagrams provide a visual notation for the concepts in each view
