Notation used in this book - UML???
Hi There, I just picked up this book recently and I'm liking the book so far - however, there's just one thing that is confusing me: The class diagrams. They don't seem to use "proper" UML notation and I can't seem to find any place that indicates what notation is being used?
For example: the class diagram depicting the Facade pattern: what is the relationship meant to be represented by the line with the solid arrow head between BusinessObject and BusinessEntity? It doesn't seem to be inheritance as all 3 classes (BusinessEntity, DataAccessObject and BusinessSession) - all seem to have the same relationship to BusinessObject.
Can you please explain this in more detail - it would be much appreciated. I like to know my material inside out.
Cheers,
