I also believe that DAO isn't necessary anymore. But I do believe that some 
helper (or service) classes are a good thing.

You would get something like this:
        
  |          view layer
  |              |
  |              |
  |         business layer
  |           |       |
  |           |       |
  |    services layer |
  |           |       |
  |           |       | 
  |         db entity layer
  |
