Amen to that. Like I said, I just work here, and I hope nobody gets the idea that I am in any way responsible for the (so-called) design. If it's possible to have a normal form with a negative number, then you will find it here.
Just to share with you a little recent event: Somebody wanted some entries deleted from a table based on a date range. So the person doing the deleting had just enough command of SQL to be dangerous and deleted from the table where COLUMN between 'date_string_1' and 'date_string_2'. Now, if you will, please note that this is entirely a string operation. For some reason known only to God, the date is stored as a string. And guess what happened.
Anyway, it was good experience for me since I got to have rman create a duplicate database on another box and do a point in time recovery. It's been quite a while since I've done that, and I was getting a little bit rusty.
