Re: Hiding data model

  There have been many times where I have contacted software vendors to report errors in their application code, or even their design. And to supply the fixes.

   Why would you choose to cut yourself off from thousands of free troubleshooters, some of whom are probably better than any you can afford to keep on your own payroll?

   That aside, a common side-activity for DBAs is to *evaluate* potential software purchases. When faced with competing products, one with a well-documented data model and the other with a "closed" or "obfuscated" data model, I will always favour the open one. The better I am able to understand a product, the better I am able to support it.

   You can be certain that an obfuscated data dictionary will shut you out of at least some sales opportunities.
