Hi Tricia,
I would add to Johannes' answer those advantages of DAOs
(http://java.sun.com/blueprints/patterns/DAO.html) :
The Data Access Object (or DAO) pattern:

Johannes,
I have successfully refactored my code with your last update of the wiki

Hi Johannes,
Thanks for your work on this! I'm currently in the process of setting
up hibernate 3 with cocoon 2.1.10 and have been back and forth between the
the tutorials (simple application) at
