SQL

What's the best tool you've used for large-scale database design? Besides emacs, I mean.

Flat configuration files are usually sufficient, if not superior (because of their simplicity).

I normally just use a scheme like this:
define variable value
or
(define (variable)(value)) (get it? Scheme! hahahaha!)
If I need sections or whatever, INI is good enough. I don't really like JSON.
