title: Shouldn't the wordpress database be Normalized?
body: <p>I just started learning the custom wordpress queries and came across the wordpress database. I was just astonished to see that the database wasn't normalized. I mean it'd be okay to use such a structure (i.e. having redundant data) in case when you haven't immense data but what if you have a large data. It would have less performance, wouldn't it? My question is:</p>
  
  <p>Why would such a reputed product use an denormalized database? Are there any specific reasons behind?</p>
