I've spent a fairly small amount of time so far trying to use ActiveRecord, and none 
at all yet with OG.  I decided that, conceptually, i preferred the AR approach of 
generating methods from an existing database schema.  After working with it a little, 
though, i have to say that i really don't like AR.  Creating various associations 
(has_one, belongs_to, etc) seems much more cumbersome to me than what i would hope to 
be able to do by simply writing a sql query wrapped inside a method where i can 
assign the values returned from the query to ruby variables.  This seems like it 
should be simpler to code, easier to work with, and more flexible.  There may 
actually be a way to do this with AR but questions to the mailing list haven't 
resulted in anything very helpful to me at the stage i'm at and the documentation is 
dreadful.  I wonder if OG could provide the kind of interface i'm alluding to?
