ARCH-2: UML 101 - From Design to
Implementation using UML
Frank Beusenberg
Senior Technical Consultant
Theory vs. Practice
The difference between
theory and practice is that, in
theory, there is no difference
between theory and practice.

Introduction
What is UML? Facts
 UML = Unified Modeling Language
 First UML spec in 1997
 Current version = 2.0
• Object Management Group (OMG)
 Graphical language
• Object Oriented in nature
• Has syntax rules
• Can be extended using stereotypes
 NOT a methodology!

Introduction
Why model?



Manage complexity
Mitigate risk
Facilitate communication

Modeling provides ability to visualize entire systems,
assess options and designs
• Software has grown from do-it-yourself into highly
complex systems
• Software is integral part of business process, so has to
be well planned
• Software has become capital equipment that cannot
just be removed/changed

Introduction
Why use UML?
 Specify, visualize, and document models of
software systems
• Current and new systems
• Structure and design
• Behavior and interaction
 De facto standard (Tool Support!)
 Unambiguous and consistent notation
 Documentation
