Hi everyone,

I'm having trouble understanding when to use table constraints vs.
column ones. I putting together a database to store events in the school
district where I work and that's where the constraint question comes in.
If anyone has a few minutes to kill, I'd love to get some feedback on my
design at http://www.isd197.org/sibley/staff/wilsont/event_product/

You can see it's a work in progress. The more interesting stuff is
toward the bottom of the page.

-Tim
