UML 2.0 Video Tutorial

UML 2.0 Video TutorialWelcome to myย UML 2.0 Video Tutorial! In this series I will cover Use Case, Activity, Class, Object, Sequence and many more UML Diagrams.

Unified Modeling Language (UML) is a graphical way of describing software systems. In this tutorial, I’ll focus on Use Case Diagrams which list the steps a system needs to follow to reach a goal. I’ll walk you through the parts of a Use Case Diagram as well as the requirements of aย Use Case Description.

It starts slow, but quickly it will dramatically improve your ability to create robust systems.

    Hello Derek,

    I am sooo enjoying your tutorials. I am working the UML track, and found parts 1, 3, 4, 5, and 8 but I have to start each one to know the sequence number, and well, I can’t find number 2 at all. Your tutorials are fantastic. Please keep up the great work!

    Great tutorial Derek,nice website its been a one stop shop for me soooooooooooo…. Much content. I’m in college doing computer programming 101 we’ve covered Java,GUI and we’re doing SAD now and your vid’s have been invaluable to me and I’m sure too many other people aswell, you cover EVERYTHING Thanks and keep up the good work.

    Although one programmer has the necessary skills and knowledge to work competently on a problem or even create a program, he or she can only do so much. Creating the source code for an operating system, for example, will require thousands of manhours from a single programmer and most probably, he or she will only be halfway through. There just isnโ€™t enough time for one or even two programmers to work effectively to produce a usable program.^*

    All the best
