title: relationship between DAO and hibernate
body: <p>I tried to google the answer, but I am still puzzled about their relationship.
  I speculate Hibernate is a kind of DAO. 
  And I looked up DAO in Wikipedia, 
  <a href="http://en.wikipedia.org/wiki/Data_access_object#Tools_and_Frameworks" rel="nofollow">DAO</a></p>
  
  <p>But found there is nothing related with hibernate there. So what exactly is the relationship between the two? Some examples will be great!</p>
