I just would like to know what are the advantages of using a DAO object to Entity bean?

In the MVC pattern where can we group the DAO object?

Advantage of using DAOs over entity beans is because of its performance.
DAO's should sit between ur entity beans and database in the architecture

Karthik,

Can you please re-check if DAO's are used just before Entity beans, as What I have experienced is DAO's are a substitute of Entity Beans and the DTO or VO's are the Objects which are used just before Entity beans.

Karthik, Can you please verify or correct me or anybody if I am wrong anywhere.

Thanks,
Rahul Juneja
