Yes, I agree. The disciplines of man might like to think themselves unrelated to one another, but they share common problems.

I have thought about this, and concluded that the greatest (and single most cost-incurring expense) related to database systems is RE-definition of data ---- once in the database, and again in the code (wherever the code may actually reside)

Here is one possible method of formalisation: http://www.mountainman.com.au/software/Theory_of_Organizational_Intelligence.htm
