   RE: [xml-dev] ISO and the Standards Golden Hammer (was Re:[xml-d ev] You

[ Lists Home | Date Index | Thread Index ]

It was the IDEs and the position that if the code validated the 
file, who needed a data dictionary?   Just had that discussion 
with a programmer and his manager last week.  The programmer 
considers it just a document to show a customer.  Our certification 
chief has other ideas.  Our manager thinks it is the best way 
to keep lots of independent minded, IDE equipped staff in line.

I'm surprised at this perception. My recollection is that when data
dictionaries were popular, everyone knew they had to call it
"LAST_YEARS_NET_REVENUE" rather than every programmer making up their own
cryptic abbreviation; what's more, every screen that it appeared on used the
same validation rules. I've always felt that the data dictionary was one of
the good ideas of the 1980s that we've lost. An XML Schema is a partial
substitute, but a very poor one. 

Perhaps it's another European idea that never really caught on in the
States. Certainly, it was the advent of the RDBMS that caused its demise.
