Well, that's what I thought I was doing with my compound key of arttype and artid. They behave as though there is a coordinates table, except that table doesn't really exist. >Similarly, you have people entities, but a 'people' can be a person, a >function (company sales manager) or a group (eby family). People have data (birthdates, nationality, first, last and middle names) that bands don't have. I guess I can put in a bunch of extra fields that will only be used for people. I thought that would violate some kind of normalization rule. Not that I can actually recognize normality when I see it. >Yes, it is all good clean fun, until someone loses an eye. Then it's >good clean one-eyed fun. That usually happens when one attempts to apply "Red Ryder Normal Form".
