UML Cheatsheet | Class Diagram Resource

Last updated May 19th, 2022
Here's a handy-dandy UML cheatsheet.

UML class diagrams can be a useful tool for communicating designs with other developers - or just drawing out your design candidates before diving into code.

I've put together a helpful UML cheat cheet based on an old (yet slightly inaccurate) one I printed out in my office when I first got started with object-oriented design.

While you don't have to be a UML pro, I recommend at least understanding how to read it. Consider downloading the following image, printing it out, and putting it in your office as well!

Software Essentialist ⚡

I'm Khalil. I turn code-first developers into confident crafters without having to buy, read & digest hundreds of complex programming books. Using Software Essentialism, my philosophy of software design, I coach developers through boredom, impostor syndrome, and a lack of direction to master software design and architecture. Mastery though, is not the end goal. It is merely a step towards your Inward Pull.
