User:Zolta/My understanding of UML

Okay. I know UML is a notation not a methodology. I'm learning Object Oriented Analysis and Design and all the stuff related. That means POJOs.

dependency
A dashed line with an open arrow points from the client to the supplier (client depends on supplier )

permission dependency
A permission dependency («permit») signifies that the supplier grants the client permission to access some or all of its constituent elements.
