[CST-2] UML class diagram

[Shu Yan Chan]

The definition of the dependency link in a class diagram is not defined in
the notes,
I searched the Internet and founds the following definition, anyone would
like to comment on that?

The dependency link is a semantic relation
between the source and target elements. It
indicates that when there is a change to the
target element there may be a change
necessary to the source element. You can
label the dependency link and set the
stereotype.

However, I am really interested in how do 'Unusual dependency relations
between classes'  can help one to spot that there is no proper encapsulation
in the o-o design?

Thanks.

Yours,
Shu Yan
