457.0. ""Open SQL"" by SNOC02::PHILLIPSB (Blair Phillips - sws Canberra) Sat Oct 14 1989 15:31
One of the local computer comics has a story on something called
"Open SQL".
The lead paragraph says:
SAN FRANCISCO - Users could take a giant leap forward in solving
their SQL database interoperability woes if a new stabdards group,
tentatively called "Open SQL", can meet its goal of producing a
common SQL application interface (API) by early next year, followed
by a reference model in late 1990.
The rest of the article gets increasingly incoherent, and it is not at
all clear whether the proposed standard is for an API or for an
interoperability interface between databases, or both. (Actually, I
think that the SQL Module Language makes an adequate API, so I don't
see the need for another.)
The article says that the initial membership consists of Tandem,
Informix, RTI, Digital, Hewlett-Packard, NCR, Sun and Teradata.
Can anyone shed some light on this group? In particular, what
interfaces is it aiming to standardize?

| This story was leaked to the press by some of our friends at "RTI". The other
20 plus members of the group have agreed to be silent about this until our
formal press announcement next week. The Computer World story has lots of wrong
information in it.
Here are some facts about the group:
The group was started by Digital and Tandem earlier this year and today has
grown to over 20 plus members.
The name of the consortium was changed to SQL Access. RTI after joining the
group renamed their Common SQL Architecture to Open SQL and trademarked the
name.
The consortium will define and implement a set of specifications based on the
existing SQL standard and RDA standard. These specifications when incorporated
in database and application programs, will help achieve true interoperability by
allowing users to work across different database systems.
The consortium will publish a technical specification, which will include a
standard (API) application programming specification as well as a Formats and
Protocols Specification (FAP).
ISO/SQL defines a syntax to access SQL data. The syntax (API) gives
source-level portability among SQL systems. ISO/SQL does not provide syntax to
access remote SQL data or servers. SQL Access defines some syntactic extensions
to ISO/SQL which will allow the application to name and access remote data on
servers. The language chosen by the group for the API will be ANSI SQL2
Dynamic SQL (Level 3).
The FAP defines message and formats for SQL Access requests and replies as well
for connection to an SQL Server. Data types, lengths, and representation are
also defined by the FAP. The formats for data streams that flow between a
client and a server are also defined.

| I guess this explains why Sybase have suddenly renamed their server to
Open Server and their client to Open Client.
Do you know if SQL services in Rdb uses RDA ? The local defence dept
is real big on OSI standards and have been asking about our support for
all these wierd standards most of us have never heard of.

| No, RDA isn'tthat close to being a standard yet.

| Well, yes sort of. Ask for details in the SQL SERVICES conference.
