To Derek Webb: damn bro, you make DB design and understanding as complicated as a rocket science. Dude, it's not that complicated. Anyone who had done DB rational design or algorithm in college/university, they can look at a database design and point out what's wrong and whats not. Most design can go through simple algebra and normalization process. Sometimes DB designers ignores them for flexibility and for other issues. Not a smart move, but has been practiced by many big companies, and drupal is an example.

I don't understand why someone with good Db designer has to look at the same db structure for few years to make comment. you are hilarious.
