I recently came across Chris Date's article

http://www.dbdebunk.citymax.com/page/page/622867.htm

I think even the kindest reader of Booch, Rumbaugh, and Jacobson's book, THE
UNIFIED MODELING LANGUAGE USER GUIDE, could agree that Date makes his point,
that the explanations of OO concepts in the book are not coherent. Can
someone suggest a book or preferably an article where the authors expound
the concepts with clarity and precision?
