[CFCDev] Should bean extend DAO ?

[Marcantonio Silva]

Hello,   Is it good or bad design to make my beans extends the DAO ?   I mean, an "animal" bean is not exactly a specialized animal DAO, but I could call the save, update and delete methos directly from the "zoo" Facade if I extend animalDAO from animal.   The difference would be in the bean, if I extend the DAO, I would not have to instantiate it in my init or pseudo constructor, and could call the DAO CRUD methods easily from the bean body. On the counterpart, it seems as I already mentioned, that the DAO methods would be exposed to the outside world, an this just don't feel right for me (hmmmm ... maybe that's one of the reasons for a Transfer Object to exists).   Anyway, is there any good or bad argument against it ?   []s Marcantonio Silva Diretor de Desenvolvimento de Produtos - Navita [EMAIL PROTECTED] www.navita.com.br Tel: +55 11 3055.2004 Cel: +55 11 7732.4907 (novo)
