A few warnings that you might be in over your head:
Sixty-six percent or more of your columns for a particular table are primary keys.
If you have more than oh, say, 20 columns in a single table, put some serious thought into why you’re doing that.
You have a table named BAD_MAIN.
You start to create new BAD_MAIN tables monthly.
Ok, BAD_MAIN might not be so bad, I just find it funny.
evrytg is abrvd so u dnt hv 2 typ (or ndrstnd) as mch – ALLTMT_PRD_MO_NBR. Seriously.
