Hi, everybody,
I am wondering the first step for UML would be use case, but then how
could I get normal object model which means those static model, and t
hen make interoperation to optimize static mode?
Because use case analysis can't provide class diagram, so where the cl
ass diagram come from? Still come from rule of thumb?
thanks.

what you mean the use case analysis is not the actual one, you just me
an
the use case view,there are four other views:logical view,component vi
ew
process view,deployment view.
The development step is:get the full and actual requirement,use case a
nalysis,architectual
analysis,architectual design,use case design,subsystem design,class
design.
First design the sequence diagram in logical view,the system will auto
generate the collaboration diagram,then based on the logical view
design the class diagram.

Hi, thanks for your comments
I exactly know what you mean, but I think that's not what I am asking.
See, I checked some tutorial document, and all of them say that after
User-cases diagram is finished, then would be Domain Analysis which c
reate Domain Class, I cut off a pragraph from one of them and paste be
low, pls check out.
"Reauirement Analysis: Besides defining the functional requirements of
the system, use cases are used in the analysis to check whether the a
ppropriate domain classes have been defined, and they can be used duri
ng the design process to confirm that the technical solution is suffic
ient to handle the required functionality. The use cases can be visual
ized in sequence diagrams, which detail their realization.
Domain Analysis: An analysis also itemizes the domain (the key classes
in the system). To conduct a domain analysis, read the specifications
and the use cases and look at which "concepts" should be handled by t
he system. Or organize a brainstorming session with users and domain e
xperts to try to identify all the key concepts that must be handled, a
long with their relationships to each other. "
So, does it mean Domain Classes are still come from rule of thumb?
Thanks for any comments.
