Well, not exactly, or not really what I was thinking of.  I meant one
can define a class, with whatever properties and behavior, and Rails
would determine the proper database structure from my actual class
code, not from a separate Ruby command to go create a table.  But being 
able to avoid running a special configuration too, (i.e, a SQL editor or 
admin GUI) in order to write Ruby is a plus in any event.

An annoyance I have with Rails is that when I want to see if an object 
has some particular property I have to go run an SQL app or look 
someplace other than in the class definition.

The code at

http://api.rubyonrails.org/classes/ActiveRecord/Migration.html

suggests that the object/table definitions are occurring someplace other 
than in the class definition itself, something I'm not quite, um, 
"jiggly" with.
