The primary author of the dbdebunk website places quotes he considers to highlight issues in understanding of the relational model by the unwashed. Fabin Pascal hates OODBMS and considers the whole of OO to be a dead end in computer science that should have been aborted awhile ago. He links to several sites critical of OO.

The main thing to take away from his criticisms, IMO, is that OO is not suitable for data management. OO as an application programming paradigm is not necessarily a bad thing, and Pascal doesn't really get into that area, since his interest is in data management.

... then a equally loaded RDBMS(or as Pascal would rather put an SQLDBMS)

By saying this, are you trying to imply that there's no difference? There is a huge difference. You may not know what makes them different, but you cannot equate the two.
