Quote:> Remote Database Access using the SQL/RDA protocol ?

Does anyone have experience with RDA?

RDA is client/server application layer protocol for the remote querying of
multiple different vendor databases over TCP/IP and OSI

I'm examining the RDA ver.2 spec. and would like to know of;

1) successes
2) problems
3) development

Thank you,

Stephen White

Several years ago, I was involved with the SQL Access group implementing
RDA, which led to a
interop demo in July of 1991. For details, see IEEE Computer, December
1991, "SQL Access:
An implementation of the ISO Remote Database Access standard".

Unfortunately, RDA has never really taken off; it has been supplanted by
ODBC, which solved
*some* (though hardly all) of the heterogeneous client/server problems.
However, there are
a few companies which have pursued RDA for some narrow markets;
unfortunately, I don't have their
names at hand right now.

Good luck.
