title: MVC : Should the Model layer only contain DAO and DAOHelpers?
body: <p>what you think should be present in the Model Layer ? Only DAO and DAO Helpers ? what else could be present ? Logger ? what ?</p>
  
  <p>I am designing my first app and yesterday I had a Model helper class that could be used in, but I was not sure where I should put it.</p>
  
  <p>It was a Data Fetcher and formatter class, for some types of things of my app.</p>
  
  <p>Cheers.</p>
