Quoting scrame in a comment on a "MOVE" design pattern as proposed (http://cirw.in/blog/time-to-move-on/ ):

In Java/Spring-MVC, there is a typical class hierarchy of Controller -> Manager/Service -> DAO. The extra level of indirection is a very handy place to put business logic, then each class in the tier has a dedicated function:

  • Controller - Parses input, delegates the action and returns the response (rendered by the view).
  • Manager - Handles sanitized data, encapsulates business logic and makes calls into the Model / Data layer.
  • DAO - Interfaces with the data store, makes sure only good data goes in, and appropriate responses are returned.
