Hi Mark!

This type of diagram is called the UML class diagram. You can find lots of info about these diagrams over the web, as the UML is a major standard. A nice starting point is this wiki page: https://en.wikipedia.org/wiki/Class_diagram

Just FYI, the brief intro into UML is also present in the full design patterns book ( https://refactoring.guru/design-patterns/book )

Yes I have purchased the book right after posted here. I'm excited and I think i'll learn alot on this book.
