At my University I have a module Requirement Engineering.
We have to do UML Use Cases and I understand 99% but I have one question.
I have a Use Case “check password” that is an <> from “login email” and “login Facebook”. Once it is checked on the app itself (login email) and once it is Facebook that checks it (I suppose Facebook is another actor) Can I use the same Use case “check password” or do I need a separate one? or do I just don’t check the password from the “login Facebook” and connect it directly to Facebook. Do I have to do the same for output Error.
I know everything is German sry
I hope someone can help. I have always been lucky here.
Thanks for reading
