Jan,



what is your take on Garcia-Molina, Ullman and Jennifer Widom
regarding their stand on duplicates?



(see http://www.dbdebunk.com/cjddtdt.htm and cjddtdt2)



Are they just realists accepting that SQL is the de facto
standard, so one might as well take it as a basis?



Or do they actually think that duplicates are OK
and cause no harm?
