Question about Model Driven Interface

[Umesh Awasthi]

Hi All,

Have rarely used model driven interface and not sure about how exactly it
work.
Can any one point me what will be difference between

    ProfileDTOModel md = new ProfileDTOModel();


    publicProfileDTOModel getModel()
    {

       return  md;
    }

and

  public ProfileDTOModel getModel()
    {

       return  new ProfileDTOModel();;
    }
