you have mentioned that
"You're going to have an object in memory no matter what"
If we are using Resultset how/when is the Object getting created? I was
under the impression that it will get the data directly from the DB.
what are these DTO, GC and IMO?
I do remember reading somewhere that if this approach is used then we'll be
breaking the MVC architecture.
any reference links for this?
Thanks.

You're going to have an object in memory no matter what. In most cases
DB connections are a more limited resource than memory. Besides, once
the ResultSet is translated into a DTO, it is free for GC anyway, so
you've really only lost the conversion time, which is worth it IMO.
I think that using a POJO (or POJO+) for the DTO more than pays for the
conversion time with easier code, generally more robust code, etc.
