[Dbix-class] Newbie question

[Andreas Mock]

Hi all,

I digged around the provided manuals for DBIC, but there is one (besides others of course ;-) ) things
I don't understand at the moment:

Where is the mapping done/declared between the attributes of a business object and the attributes 
of the row object returned by a ResultSet?

Which class or instance of it creates the business objects when getting it from database?
Is this part of DBIC or does DBIX just ends there?
Or (what is likely) do I just miss something?

Best regards
Andreas
