Suppose a database server and client are separated by a low bandwidth
link such as DSL, and the client repeatedly issues a query for, say, a
current product list.

Suppose the product list is large, but only a handful of entries have
typically changed between queries. It would be nice if only the changes
from last query to current one could be sent, saving bandwidth.

Is there any way to do this?

Thanks,
