Hi Steve,
All SQLnet is is a transport with a transport protocol.
The gateways "work" at the API level. For the Rdb Transparent Gateway
to Oracle the API is Rdb's API - the programs that talk DSRI. For the
Oracle Transparent Gateway to Rdb the programs that talk OCI (or a
superset of it) can talk to Rdb. The transport is just a thing in the
middle. If you have an program written for Rdb, or your programmer's
are used to programming to Rdb and you have all of the Rdb tools yet
you want to use an Oracle database for some tasks, you can use the Rdb
Transparent Gateway to Oracle. If your programmers are very used to
Oracle or have programs/tools that work with Oracle but want to get to
Rdb then they can look at the Oracle Transparent Gateway to Rdb to see
if it does what they want.
I hope this helps.
Dan
