Cmon Bruce,  You know I was talking about the DEFINITION aspect, 
Not the CONTROL aspect of data declaration.

I'm as much as a fan of OO as you are.  And I have been a supporter
of pushing the "Business Rules" into the data base for 10 years (like Codd
said)

I even have been teaching for SQL for POWERTECH lately trumpeting those
particular points(Great classes BTW,  www.400school.com plug plug)

However the DEFINITION aspect of DDS with the Refer process,  with 
it's ability to do type casting while still referring,  is still better IMO
as
stated above.

BTW,   why didn't they automatically map the VALUES,and RANGE
DDS function into the new stuff????????

That's all
