What is UML?

UML was first released by the Object Management Group (OMG) in 1997, and is currently being upgraded to version 2.0. UML is designed to bring together the development community with a stable and common design language that could be used to develop and build applications. It is a modeling language, and is programming-language independent.

UML provides various diagrams that let users capture and communicate all aspects of an application architecture using a standard notation that is recognized by many different stakeholders. There are 13 official UML 2.0 diagrams, each of which is a different view that shows different aspects of the system:

  • Activity diagram
  • Class diagram
  • Communication diagram
  • Component diagram
  • Composite structure diagram
  • Deployment diagram
  • Interaction overview diagram
  • Object diagram
  • Package diagram
  • Sequence diagram
  • State machine diagram
  • Timing diagram
  • Use case diagram

In the following exercise learn how to create a use case diagram, a class diagram, and a sequence diagram, and then publish and transform the design using Rational Software Architect.
