Uml introduction

1. Famous UML Philosophers
 Laws are like sausages, it is better not to see
them being made. – Otto von Bismarck
 Why do you climb philosophical hills?
Because they are worth climbing. There are
no hills to go down unless you start from the
top. – Margaret Thatcher

6. Object Management Group
 Modeling Standards
 Unified Modeling Language (UML)
 Model Driven Architecture (MDA)
 Common Object Request Broker (CORBA)
 Meta Object Facility (MOF)
 Interface Definition Language (IDL)

7. OMG and UML
 Define and maintain the UML specification
 Disseminate information:
 Tools and tool vendors
 Specifications
 Articles
 Resource Pages
 Tutorials
 Modeling Methodologies
 Professional Certification (3 levels)

8. OMG, UML, MOF, and MDA
 UML, along with the
Meta Object Facility (MOF™), also
provides a key foundation for OMG's
Model-Driven Architecture®, which unifies
every step of development and integration
from:
 business modeling
 through architectural and application
modeling
 to development, deployment, maintenance,
and evolution.

9. Model Driven Architecture (MDA)
 Provides open, vendor-neutral approach to
challenge of business and technology change
 Separates business and application logic
from underlying platform technology

10. MetaObject Facility (MOF)
 Models can be …
 exported from one application
 imported into another
 transported across a network
 stored in a repository then retrieved
 rendered into different formats (e.g., XMI)

12. UML and the __________ Pattern

13. UML Documents
 Superstructure (v2.1.1 Feb 2007)
 Infrastructure (v2.1.1 Feb 2007)
 Related

14. Metamodeling

15. Metamodeling

16. Infrastructure
(Metamodel)
 Infrastructure Library Packages
 Core
Defined in
MOF, reused
(refined) in
UML

17. Infrastructure
(Metamodel:Core)

18. Infrastructure
(Metamodel:Core:Abstractions)

19. Infrastructure (Comment)

 Generalizations
 Attributes
 Associations
 Constraints

 Presentation Options

20. Infrastructure (Comment)

21. Infrastructure
(Metamodel:Profile)

to have constructs for a specific domain or
platform

 The Documents
 Infrastructure
 Superstructure
 Related (UML Distilled, Diagram Interchange,
OCL)
 Presentation Opportunities

23. Superstructure – UML Metamodel
 Major element categories
 Classifiers (describe set of objects)
 Events (describe an occurrence)
 Behaviors (describe set of possible
executions)

24. Superstructure – Runtime Model
 All behavior is caused by actions executed by
active objects (e.g., a class)
 Behaviors occur because of discrete events
 Causality: objects respond to messages
generated by objects executing
communication actions

25. Superstructure – Capabilities
 Structure
 Classes (55)
 Components (4)
 Composite Structures (15)
 Deployments (12)
 Behavior
 Actions (55)
 Activities (52)
 Common Behaviors (31)
 Interactions (31)
 State Machines (16)
 Use Cases (6)
 Auxiliary Constructs
 Information Flows (2)
 Models (1)
 Primitive Types (4)
 Templates (20)
 Profiles (8)
 Group of tightly coupled modeling concepts
allowing representation according to a
particular formalism – aka language unit

26. Superstructure – Classes
 The Kernel Package

 The Kernel Package

27. Superstructure – Classes

28. Superstructure – Classes Diagrams
 Root
 Namespaces
 Multiplicities
 Expressions
 Constraints
 Instances
 Classifiers
 Features
 Operations
 Classes
 DataTypes
 Packages
 Dependencies
 Interfaces

29. Superstructure -- Profiles
 Tailor UML metamodel for different platforms
or domains
 J2EE vs .NET
 Real-time, Business Process Model, SysML
 Leverage Profiles in Infrastructure and Meta-
MetaModel
 Leverage defined portions of UML in
Superstructure

31. UML Distilled – Martin Fowler
 Describes 14 diagrams
 Distills Superstructure
into English with
commentary

32. Diagram Interchange
 Friend to UML Elements::Element
 Graphical and model information are cleanly
separated
 XMI serialization
 SVG representation

33. Object Constraint Language (OCL)
 Supplements UML diagrams
 Specifies invariants on classes and types
 Well-formed expressions
 Typed language
 Formal language with no side effects
 Can be used as a query language
