Data Model Patterns (Was: Groves and Architectural Forms)

Has anyone on the list read David Hay's 
book "Data Model Patterns" ?

His book describes patterns that arise when modeling
systems using a relational database.  It is *very* good.
I've been doing corporate database work for 6 years at
companies like Ford, GM (transitively), Gartner Group, 
as well as many small corporations.  Anyway, his patterns
hit home hard -- the models he has published are very close
to those that I came up with after painful corrections.

Anyway, towards the end of the book he gets a bit 
philosophical and proposes a "universal pattern".
It is strikingly similar to Groves.  I guess this
should be no suprise...
