| 756.1 | No Sybase support for Rdb | TRCA03::MCMULLEN | Ken McMullen | Wed Oct 03 1990 16:46 | 14 |
| Keith,
Sybase does not interface with Rdb/VMS. Just because a system is an
"SQL compliant system" does not mean that one vendor's tools will talk
to another vendor's relational database.
Sybase makes noise about their "Open Data Architecture", which means
that you could hook 3gl programs to their toolset that could read and
write to other data resource managers. But then you can do this with
just about everone's products. The problem with this approach is that
there is no way to co-ordinate updates (ie 2PC, data integrity) with
the SYSBASE tools and other data resource managers.

| Take an application view...
When you say "a customer who is considering the VAX/Rdb but has some existing
Sybase users"
Do you know if the applications they use where written with Fastbuild or
APT workbench.
If the Answer is Fastbuild, then something may be possible. Fastbuild is
Sybases version of UnifAce with restricted database drivers. UnifAce can
supply additional database drivers for the product, so you could get an
Rdb/VMS database driver from them. Once you have the Rdb/VMS driver, and
creat an Rdb database, Uniface/Fastbuild can be used to move the database
from one database system to the other. Changing a definition in the
Fastbuild conceptual schema tells the application to get data from the Rdb
database not the Sybase one.
In theory its a great idea...
On the other hand, if they used APT Workbench, you may be stuck with Sybase
unless you start from scratch.
Iain.

| 756.3 | Try Sybase's OPEN Server Product | POBOX::LACEY | ACMS/Rdb, the transaction Autobahn | Mon Oct 08 1990 15:07 | 12 |
| Sybase has announced their 'OPEN Client' & 'OPEN Server' products.
I believe you can use the OPEN Server API to write routines that utilize
Rdb. In that way a Sybase application can access both Rdb & Sybase as
if they were both Sybase databases. Sybase is already touting this
functionality for access to DB2 read/write-able.
Sounds like a neat marketing idea!!, but you have to remember the 'OPEN
Server' is not so open it uses a proprietatry API just as ACMS would
without the application knowing whether it was utilizing Rdb, Sybase,
RMS, ...
