Anything similar to EOF's client-side processing?

Howdy All,

I know there are products similar to EOF (Hibernate, Cayenne, ...) in
terms of Object-Relational Mapping.  However, I wonder if there are any
other technologies / products that do what EOF does in enabling you to
fetch business objects to a Java client application and do processing
there?

What are comparable technologies / products for Java or MS.Net?

In particular here, I am not talking about the powerful
DirectToJavaClient technology (which also includes the dynamic
generation of the Java GUI) but particularly about a semi-transparent
and automatic way to move business objects from the server to the client
and then the database in a consistent manner.

Also, going through the Web server is important too.

I know of RMI, CORBA etc, but these are more distributed object
technologies (ie object-to-object communication from one application to
another).

Just interested (and doing risk minimisation ;-)

Thanks for any pointers.

Cheers,
Ashley.
