Hi,
Ok, we can use dependencies instead of associations in Rose, but are we also able to
include them in a SoDA report ?
With version Rose 2000e it was not possible!
Kind regards
Walter

Betreff: RE: (ROSE) Bar Bet #2
Hi Eric
As Todd points out - the comments in Terry's (she is called TQ most of the
time around here) books are because Rose did not support the correct
relationships for uses/extends, and later include/extend. TQ was describing
the workarounds in those releases (Rose98 and Rose2000).
This was fixed in Rose 2000e (or it could have been Rose 2000). Remember
Rose releases went Rose98, Rose98i, Rose98i SP1, Rose 2000, Rose 2000e and
the current release is Rose2001.
The switch from uses/extends to include/extend mirrored the changes in UML.
UML 1.3 switch the terms from <<uses>> to <<include>> partly because the
term "include" gave a much better description of the purpose of the
relationship - the term "uses" had created much confusion and there was a
lot of abuse of this kind of relationship. The name change from <<extends>>
to <<extend>> was a little more subtle - and also mirror a slight change in
the meaning ("a little more subtle" means I can't remember why this happened
:-))
The correct UML 1.3 *and* now Rose relationships for <<include>> and
<<extend>> are stereotyped dependency relationships. Not associations and
not generalisations.
Hope that helps
regards
anthony
