Unified Modeling Language (UML) is a graphical way of describing software systems. In this tutorial series, I cover Use Case, Activity, Class, Object, Sequence and many more UML Diagrams. I CAN not think of anything more Important for A good programmer to Understand than UML. With it you'll be able to create first class Object Oriented Designs. Those designs will allow you to create anything you can imagine. But, without UML none of these things are possible. Every video and links to all of the code can be found below.
