P.S.  This book (http://www1.fatbrain.com/asp/bookinfo/bookinfo.asp?the
isbn=013629023X):
  Object-Oriented Systems Analysis : Modeling The World In Data  
  By Shlaer, Sally / Mellor, Stephen J .
  Softcover; 144 Pages
  Published by Prentice Hall
  Date Published: 04/1989
  ISBN: 013629023X

contains an excellent treatment of this topic.  Obviously, it's a
Shlaer/Mellor book, but the techniques descibed apply equally well to
other methodologies such as Rumbaugh OMT or UML.  In fact, the
techniques originate in the database world.
