UML is like the Grand Unified Theory (GUT) for physicists – only difference is UML has been developed and is being used everywhere. I started this book a few days ago and I am hooked. I will be telling you some of the interesting things I discover in this journey.

As a briefer : UML defines nine types of diagrams

1. Class diagrams
2. Sequence diagrams
3. Collaboration diagrams
4. Object diagrams
5. Statechart diagrams
6. Activity diagrams
7. Use case diagrams
8. Component diagrams
9. Deployment diagrams
