Re: [UML Forum] What does the arrow end of a dependency relationship indicate?

[István Dányi]

Hi Martin,

Just a thought... the answer can be correct only in the following way:

D. client element can be affected by a change in the supplier element

So in my opinion, the problem of the original sentence is the strict statement.

Hello,
i'm preparing for the OCUP fundamental test and have found some sample questions with answers.
one is regarding dependency relationship: What does the arrow end of a dependency relationship indicate?
with possible answers:
A. more general classifier
B. element initiates communication
C. whole in a whole-part relationship
D. client element is affected by a change in the supplier element
E. supplier element is unaffected by a change in the client element
correct answer is E.

why is also D not a correct answer?
using dependency relationship means telling which side of element is dependant, not independant (E must not be correct if there also exists a reverse dependency between same classes  - is that allowed?:).

definition of dependency: "A dependency is a relationship that signifies that a single or a set of model elements requires other model elements for
their specification or implementation. This means that the complete semantics of the depending elements is either
semantically or structurally dependent on the definition of the supplier element(s)."

thans for help,
Martin
