title: Swapping values around in the view with information taken from a DAO
body: <p>To respect requirements, I've temporarily used a hack to swap around a numerical id with a String representing a corresponding username in the view.</p>
  
  <p>To do this I've called a DAO directly from a TableModel. Obviously, this isn't very elegant and is probably inappropriate from a design point of view. What would be the proper approach to achieve this?</p>
