DAO - Date access Object . Generally used to when u want to have the
felxibility of changing the database . This Data Access Objects  accesses
the database . Instead of tying the business logic to one database , u can
use this patterns and get the added advantage .
U have to create the DAO for each database  . and call them from within the
Entity beans or session beans or from within the  Handler classes (  in case
of accessing Read only data from database)

Even u can make certain decision specific to database in the respective DAO
implementations . ( e.g  can have database specific queries )

For more information take a look at Design Patterns in J2EE ( Blue Print
book from SUN )
