Ah but the question "What landed me on this post in the 1st place?"

I'm a SQL DBA and I've never given a crap about schemas. I know what they are by definition, but have never once considered using them, because I'm probably too old-school. I think in terms of logins, groups, roles, and users. Now I'm in a circumstance where everybody and their mailman has had their hands in the cookie jar on this production server and nobody currently working here knows why things are the way they are. Should I create a new post to get flamed on "You call yourself a DBA....." or do you want to take a stab at answering me here?
