                AN OVERVIEW OF UML

---------------------------------------------------
                  WHAT IS UML?

- stands for Unified Modeling Language
- slight misnomer, actually a collection of a variety
  of notations such as for use case diagram, class 
  diagrams, interaction diagrams, sequence diagrams,
  package diagrams, etc. 
- More appropriately a family of graphical notations
- a standard set by Object Management Group (OMG)
- current version is 2.1.1 
- continuously evolving standard
- tools support a subset of important diagrams

---------------------------------------------------
                WHY KNOW ABOUT UML?

+ primary goal is communication and understanding
+ common lingo among practitioners (only true about
  the stable aspects of UML)
+ graphical notation, (that is easier to understand?)

- often referred to as everything and the kitchen 
  sink due to a plethora of notations that collectively
  form UML
- size makes it harder to learn

Bottomline: Learn key notations and know the purpose 
of each diagram and the difference between diagrams, 
but don't spend too much time memorizing each notation. 
Rather use a good book on UML as a reference manual.

I suggest:

Martin Fowler, UML Distilled, Third Edition,  
Addisson-Wesley, 2003.

           TYPES OF DIAGRAMS IN UML 2.0

- 13 different types of diagrams

- Broadly divided into the following categories

  > Structural diagrams such as class diagram, object
    diagram, component diagram, composite structure
    diagram, package diagram and deployment diagram.

  > Behavioral diagrams such as use case diagram, 
    activity diagram, and state machine diagram

  > Interaction diagrams such as sequence diagram, 
    communication diagram, timing diagram, and 
    interaction overview diagram.
