Uml introduction

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

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)

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.

http://www.omg.org/mof

http://www.omg.org/mda

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

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)

Superstructure – UML Metamodel

Major element categories Classifiers (describe set of objects) Events (describe an occurrence) Behaviors (describe set of possible

executions)

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

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)
