| 592.1 | or Hypercard/AlisaShare/Appletalk | SRFSUP::LANGSTON | Rdb is *the* Relational db for the VAX | Sat Mar 10 1990 02:54 | 43 |

We are in the process of preparing a demonstration for a customer with
~1000 MACs and a DB2 database on a IBM 3090. We're going to provide
them read access on the MACs to the DB2 database using VIDA for
DB2 on a VAX and connecting the whole thing as shown below.
You should be able to use the left two-thirds of the diagram (without
the VIDA for DB2, of course).
CL/1, I believe, is similar to AlisaShare and/or SequeLink.
AlisaShare is s/w and I think SequeLink is s/w (SQL) as well.
No changes or modifications to DECnet are required; this is a local area
Appletalk network connected to the Macintosh thru the ethernet port.
No other changes or modifications to the VAX hardware or software
are required.

Obviously, it requires non-Digital products. And it requires some
(minimal, I believe, at least for purposes of a demonstration)
software development for Hypercard. I don't know the details of
the Mac side of it, but I can get you in touch with the people who
are doing it.
Also, you may want to talk to Deb Wasserman, product manager for
SQL/Services. She's interested to know the extent of customer demand
for SQL/Services for the Mac.

| 592.2 | They all work | PNKFLD::BOOTH | What am I?...An Oracle? | Sat Mar 10 1990 16:02 | 10 |
| The big advantage of CL/1 is that it is Apple's product, and virtually
all Mac software will interface to it. CL/1 will be part of the
standard Mac operating system services later this year. The VAX CL/1
server is currently available.
Sequelink and AlisaShare also work well, but CL/1 has the advantage of
being the Apple product. All of them are available and will allow
Hypercard to VAX connectivity, hence Hypercard to DB2 via VIDA for DB2.

| 592.3 | CL/1 interface to Rdb | TRCO01::SANDHU | | Mon Apr 02 1990 15:02 | 8 |
| Does the CL/1 server on the VAX have a deliverable interface to
Rdb? If not what options are available.
We know that the CL/1 server does have an interface to Oracle. My
customer is very interested in the CL/1 secenario, given -.1 reasonings
etc., however they want to know about the Rdb interface. They seemed
to think there was no interface, if there is one, we can close the
deal.

| 592.4 | More on CL/1 vs. SQL/Services | CLYPPR::WASSERMAN | Deb Wasserman, DTN 264-1863 | Mon Apr 02 1990 15:43 | 11 |
| I'm not sure what you mean by "a deliverable interface" to Rdb. CL/1
is a Macintosh interface protocol that will allow Mac applications to
access various databases, Rdb/VMS being among them. It serves a
similar purpose as SQL/Services, the difference being that the
same SQL/Services API is available on multiple platforms (DOS, OS/2,
Ultrix, Mac) and is designed to work specifically with Rdb/VMS. CL/1
more general purpose, being designed to connect Macintoshes to many
databases.
Take your pick, we don't care which protocol your customer uses
as long as you're talking to Rdb.

| 592.5 | I Think it's Here | CLYPPR::BOOTH | What am I?...An Oracle? | Thu Apr 05 1990 14:21 | 6 |
| I think the CL/1 VAX Server is available. As Deb said, it should work
with Rdb, Oracle, Sybase, Ingres. Check with Network Innovations in
California on delivery, but I thought the VAX CL/1 Server was now
available.
