Chris Kanaracus has written a glowing description of the Data Modeler / Data Architect job in Hot Jobs: Data Modeler at Network World..  He has some great quotes:

If database administrators are jet pilots, then data modelers are aerospace engineers, performing the initial design work that enables production systems and applications to use data and drive business processes [David Van De Voort]

and

[E]limination round: There is a sure-fire way to weed out the phonies, according to Stephens. If a data modeler can't demonstrate what they can do with an established modeling tool, "then they're a pretender, [Jim Lanzalotto]

I've been interviewing data modelers for year and I can say that about 90% of the candidates supposedly screened by agencies have never authored a data model in their entire career.  The market is definitely in short supply of qualified data architects and modelers. 

and don't miss this:

salary range: US$90,000 to $130,000

It's a good article.  Check it out:
