there's a difference: the schema design is often (well... in big schemas
always) done by "drawing" a "pseudo schema" first: the logical
composition of the tables, and *then* you "fine tune" the whole thing by
applying indexes and other stuff. here we *always* use a graphigal
schema designer like oracle designer. doing so, you just have a better
vision of the whole database. the create table 'n stuff becomes a
secondary knowledge.
