Most of the other people in the class have accepted their fate and gone with fictional businesses, i.e. - mechanic shop, snow plow business, car wash, blah blah. Essentially, their databases will end up as virtual clones of the sample databases we used in the first class. I'm just trying to do something with a more unique structure/subject that hasn't been done a million times and isn't just available on the internet. I'm not actually interested in becoming a database admin (barring something amazing happens during this class that changes my mind); it's just one of the class sets I have to take along the way.
The bar code thing sounds like it could actually have a useful reason for having a database if it becomes large enough to really warrant it, and heck, I would envision that research for the XXX database would at least be enjoyable.
