You can just hear it now: At the table down the hall, there’s a group of people having, (as it seems to you) yet another academic discussion on the merits of third-normal form and the structure of primary keys. You’ve heard many discussions like this before — it all seems so pointless. After all, doesn’t it just boil down to “create table” commands and a bunch of DDL?
