Subject: Session - > DAO - > CMP 2004-06-09 - By Koala

Hi,
I would like to know if it makes sense have DAO in front of an entity
bean CMP. For example:
Client --> Session Facade --> DAO --> EntityBean
Probably this scheme could have some advantages:
1) the back end (DB or XML file) is abstracted. (I can abstract an XML
file behind a CMP bean?)
2) I can move my application written in DAO quicly in EJB without
changing client code.
and so on.
But, if I am writing a new application, does it make sense use this
schema? If so, what are the advantages?
Thanks for your help in advance.
PS
if you have links talking about this use of DAO please let me know.
(Do not send me mail of sites talking about general use of DAO).
