title: Zend framework data mappers and relations?
body: <p>How to use relations with data mappers? The example in the quick start is missing a little info how would I work with a datamapper if I am working with relational data.. For example the </p>
  
  <p>(table)User
  (table)Articles
  (table)Tags</p>
  
  <p>User -one_to_many- Articles -many_to_many- Tags</p>
  
  <p>If I get one user through the data mapper what would be the best way to get the related articles and tags? Should they be defined in the model too? Any example or best practice?</p>
