UML and Object-Oriented Design Foundations

The best-selling UML and Object-Oriented Design course on Udemy (Updated October 2021). Companion eBook included.

Explore the fundamental concepts behind modern, object-oriented software design best practices. Learn how to work with UML to approach software development more efficiently.

This course will help you become familiar with the fundamentals of object-oriented design and analysis*. I'll introduce each concept using simple terms, avoiding confusing jargon. We'll focus on the practical application, using hands-on examples you can use for reference and practice. 

(*)Many universities across the world require their students to complete this course as part of their Systems Analysis and Design curriculum.

Throughout the course, I'll walk you through several examples related to software design and UML. Plus, we'll delve into a case study to review all the steps of designing a real software system from start to finish.

What qualifies me to teach you? I have more than 25 years of software development expertise. I've worked for companies like Apple, Siemens, and SAP. As a software architect, I have designed and built several enterprise systems and frameworks, including core components of Siemens Healthcare's syngo image processing system. I'm one of the senior software architects behind the SAP Cloud Platform SDK for iOS, a framework built by Apple and SAP. I currently hold twelve patents related to inventions in the field of mobile computing.

Topics include:

  • Understanding software development methodologies

  • Choosing the right methodology: Waterfall vs. Agile

  • Fundamental object-Orientation concepts: Abstraction, Polymorphism, and more

  • Collecting requirements

  • Mapping requirements to technical descriptions

  • Unified Modeling Language (UML)

  • Use case, class, sequence, activity, and state diagrams

  • Designing a Note-Taking App from scratch

You will acquire professional and technical skills, together with an understanding of object-orientation principles and concepts. After completing this course, you'll be able to understand the inner workings of object-oriented software systems. You will communicate easily and effectively with other developers using object-orientation terms and UML diagrams.

    software development

    It taught me software development is more than just coding.

    Yes, it´s fine with news concepts about software development.

    Its very good that software development methodologies are covered very crisply before jumping into UML.

    It's teach you very importats faces of the software development using UML.

    Might be better if it was divided into the different phases of software development and get a bit more deeper in each phase.

    I am a software development college student and this course helped me A LOT with my studies and tests.

    Very perfect for me as am lighted deeply on the software development processes This course is the best online course I have evertaken.

    uml diagrams

    Poor instructor.. Great course for an overview of OOP principles and UML diagrams for those systems.

    Not only the UML diagrams have been explained, but also the big picture of how the process of creating applications looks like.

    Thank you for helping me understand the importance of UML diagrams, and clarify my concepts of them!

    You'll get up and running quickly with UML diagrams.

    case study

    Maybe a little more complicated case study than a note taking app.

    -There is a case study part for using the things you learn during the course.

    I originally expected more detailed case study.

    I really loved the case study.
