UML 2

A brief introduction

David Kemp. Melbourne Patterns, July 2006

David Kemp, July 2006 UML 2.0 2

Presentation Outline

What it is. How it is used. Its history. The Diagram Types (most of them!)

Much of the material in this presentation is based on Martin Fowler, UML Distilled, Third Edition.

What is the Unified Modeling Language?

Is a family of graphical notations. Is for describing & designing software.

Can also be used for conceptual models. Has a formal underlying meta-model. Controlled by the Object Management Group.

Consortium (also responsible for CORBA).

David Kemp, July 2006 UML 2.0 4

How is it used?

UML as sketch Describe some aspects of a design. Describe a design pattern.

UML as Blueprint Aim for completeness Forward & reverse engineering

UML as programming language Executable UML.

History of UML

1980’s and 1990’s : Dozens of OO notations. 1989: Object Management Group Founded 1991: OMT (Rumbaugh)

Used by GOF Design Patterns.

1995: Unified Method 0.8 (Booch & Rumbaugh)

1997: UML 1.0 & 1.1 (Adopted by the OMG) 1998, 1999, 2001, 2002: Versions 1.2 to 1.5 2000 - 2004: UML 2.0 Today: Work happening versions 2.1 and 2.2
