The Emergence of UML
The Unified Modeling Language (UML) is theOOD&A Equivalent
of Java
Unifies Booch, Rumbaugh, and Jacobson
Overview of UML Presentation What is UML?

Modeling Constructs and Diagrams Use-Case Diagrams
Class Diagram
Behavior Diagrams
Interaction Diagrams
Implementation Diagrams

What is UML?
UML is a Language forSpecifying,Visualizing, Constructing,
andDocumenting Software Artifacts
What Does a Modeling LanguageProvide?
Model Elements: Concepts and Semantics
Notation: Visual Rendering of ModelElements
Guidelines: Hints and Suggestions for UsingElements in
Notation

The Seven Goals of UML
1. Ready-to-Use, Expressive Visual Modeling Languagethat
Promotes Development/Exchange
2. Extensibility/Specialization of Core Concepts
3. Independent of Programming Languagesand Development
Processes
4. Formal Basis for Understanding Language
5. Encourage Growth of OO Tools Market
6. Support Higher Level Design ConceptsCollaborations,
Frameworks, Patterns, etc.
7. Integrate the Best Practices of All OOD

What Defines a Model?
Languages Defined by Syntax: Constructs and Syntactical
Context
Semantics: Meanings of Different Constructs
Pragmatics: Operational Semantics of System
In Programming Languages: Syntax: Lexical Analysis and
Parsing
Semantics: Attribute Grammars/Translation
Pragmatics: Dynamic Runtime Environment
How are Models Defined? Semantics
Visual Presentation
Note: Can have Syntax and Pragmatics!

UML Modeling Diagrams
Static vs. Dynamic Perspectives
A Diagram Is a View Into a Model
Presented From the Aspect of a Particular
Stakeholder
Provides a Partial Representation of the System Is Semantically
Consistent With Other Views
In the UML, There Are Nine (+4)Standard
Diagrams
Static Views: Use Case, Class, Object, Component,Deployment
Dynamic Views: Sequence, Collaboration,
Statechart, Activity
