1. Quote of the Week
I like a GUID as a primary key on every table so that I can uniquely identify that row. For consistency I'll call it "UID" and defined as a NewSequentialID. I'm aware of the various discussions that have been had regarding Guids vs sequences vs COMB etc., etc., but for me any performance issues have occurred in the size of databases I've worked with. The ability to create a new UID as part of an insert is of huge benefit to reduce round trips if you're handling that kind of thing from within a business layer outside of the database server. --LinkedIn.com
