UML

  • It is a family of visual, diagrammatic specification languages that facilitate the specification of both software systems and process models for their development.

    Four basic categories of diagrams:
  • Use case diagrams
  • Structural diagrams
  • Behavioral diagrams
  • Implemenatation diagrams.

    Use case diagrams: Capture the functional requirements of the system.
    Structural diagrams: Describe the static structure of the application
    Behavioral diagrams: Describe the dynamic behavior of the application
    Implementation Diagrams: Describe the physical system structures and runtime entities.
