    Design Pattern Question

    843853
      Lets say in an application there are the following components

      Database
      |
      |
      V
      DAOLayer
      |
      |
      V
      BO LAYER
      |
      |
      V
      Servlets
      |
      |
      V
      JSPs

      What design patterns does the above incorporate?
      My guess - DAO pattern.
      Is this a good enough design for a SAAS(Software as a service) application?
      What would be the drawbacks of this design?
      How could this design be made better?
