Hello everyone! My problem is kinda specific, I don't even know if there are different UML notations available or its just all about me not understanding it well. I understand the arrows for inheritance and diamonds for composition or aggregation.
I am actually reading Object Oriented Design Pattern from Gangs of Four, and I think this is there official and here is the title:
Design Patterns - Elements of Reusable Object-Oriented Software
I use it most of the time to check out for patterns that I might need. Also I having difficulties in reading the diagrams in there. I don't understand it at most.
Just like in DB we have crow's foot notation to explain the ERM, i don't know if they used different UML notation for their notes?
What is it called? Are there any visual tutorials that I can know what those lines and shapes are for?
Here is an example..
