Since DAO have two implementation : mysql and hibernate

and mysql dao throws SQLException, while hibernate dao throws HibernateException

So we need a DAOException to represent the database error in dao layer, 

that is : wrap the two exception in DAOException

and web interface is only aware of DAOException



Todo list:
---------------------------------------
add DAOException to DAO interface
