2. Exercise Keep you answers crisp!
Consider the models on the following slides and answer the
following questions. Each model is provided with a hyperlink
to acknowledge its source and for additional information.
(2 pnts) What building blocks do you see? What do they represent? Are they conceptual or physical?
(1 pnt) Same questions as 1, but now for connectors?
(3 pnts) To which views (1..*) does the model belong?
Motivate why, and identify corresponding stakeholders and their concerns.
(2 pnts) Which of the following EFRs are addressed (Y + motivation | N)?
Performance/scalability, availability/reliability, security, maintainability, other?
(1 pnt) Is there a concept of distribution (Y + motivation | N)?
(1 pnt) Comment on the clarity/semantics of the diagram
 |  |  , plus motivation
Keep you answers crisp!
