Performance is frequently one of the last things on peoples’ minds when they’re developing a system.
Unfortunately, that means it usually becomes the biggest problem after that system goes to production. You can’t
simply rely on getting a phone call that tells you that procedure X on database Y that runs on server Z is running
slow. You have to have a mechanism in place to find this information for yourself. You also can’t work off the
general word slow.
Datatype of any column can be changed if all rows of the column
contain nulls. Size of a character/raw column or the precision of a numeric column
can always be increased. Size of a datatype of a column can be reduced as long as the change
does not require data to be modified

I never thought I’d be writing a technical book. I have a MA in English Literature so I always pictured
myself sitting in an oak paneled room surrounded by books and attentive students listening to me
pontificating on the latest criticism of 19th Century novels. It didn’t take me long to realize though that
path wasn’t for me and I really wasn’t cut out for a life in academia. But now I was an ex-English major
working in a book store, starting a family and with little career prospects.
Working in a bookstore did offer some advantages.
