UML 2.0 Tutorial

Support me on Patreon :

Welcome to my 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 a Use Case Description.

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

    Thank you! That is really great to get to know how coding is connected to design of software.

    Thank you very much for the videos. I'd like to suggest just one thing: I understand each video is a string of short 'strings' (pieces of audio). Many of them starting with '…and'. There is no pause between the segments, and sounds artificial, and makes the video sound boring (long-winded). Please consider inserting 1-2 seconds! This is somewhat equivalent to using paragraphs instead of a looooong text.

    Great video as always! Btw, shouldn't the use case "stolen card" extend "verify card" and not the other way around?

    Derek, your tutorials are killer! I love your diction too. I just have one suggestion, when you show slides it would be wonderful if point that's being talked about was in different color to distinguish it. Anyway, just a little observation. Thumbs up as always!

    Summary:

    UML (Unified Modeling Language)

    Use Case:
    Defines how your program solves the problem. Defines what is required and how those requirements are met.

    Trigger:
    What is going to happen before the system is triggered
    -Machine received a card

    Actors:
    People outside of the system boundary line.
    -Customer, Bank Security

    Preconditions:
    The conditions that must be true for the system to be able to start operating.
    -Bank has cash

    Goals (Successful Conclusion):
    -Provide customer with funds
    -Secure client accunts

    Failed Conclusion:
    The situation in which system has failed or has ended processing before going to entire use case.
    -enter invalid card
    -ATM has insufficient fund

    Extensions (Alternatives):
    -If the card is stolen

    Steps of Execution (Requirements):
    -Customer inserts the card, etc.

    Hello sir, i have doubt.Can be the use case diagram used as graphical use case specification?

    Derek, When it comes to the Use Case description, it looks like you demonstrate a single description for the entire diagram. But your example is pretty much showing what the diagram itself says in the Use Case elipse. Shouldn't the description say something more? Add something and not just repeat the diagram? Also, what about a short description for each use case elipse? Thanks for the awesome, high quality videos!

    I always feel like directly skipping a topic if you haven't made videos on it. I hope you make a more comprehensive series/in one video for OOMD/UML

    okay, but the ATM Machine does other stuff (Saving/Pay loans/Transfer/Mobile credit/ec.) for the different type of customers (Credit card/Debit card/etc.) how do you fit all that into one use case diagram? Will not it be messy?

    Hi, Derek Banas. Great tutorial. However, I have a question to ask.
    For the use case diagram you used as an example, shouldn't extend be pointing to the parent use case instead? So in that example, shouldn't 'Stolen Card' be pointing to 'Verify Card'?

    Is it a good idea to start a PHP project with building a UML model? I would like to have, among other (more particular) documentation, a description of a project of a high level of abstraction. Would UML be the right tool for this? Are there any alternatives?

    i do not really understand how one could clearly separate coding and testing in the waterfall model. Noone just writes 10,000 lines of code without running the program and then gets 1000s of bugs and tries to fix them. You have to test very often in the coding process, otherwise you do not see what you are actually coding. I think it is important to do quality assurance at the end to find all the bugs that are hard to produce and that the programmers themselves´did not find directly, but a little testing has to be done all the time.

    Derek, is that possible (although not usual) use UML to modelling not just for OO languages, but other kinds too? Can you do some reference to comprove it?

    Trying to defend myself that is it not exclusively used to OO…

    Cheers from Brazil!

    Thank you as always!
