Attached below is information that I have posted previously on RDA and the
SQL Access Group.
There are two efforts underway. One concentrates on the protocol across
the wire: ISO OSI-RDA. The other is dedicated to advancing ISO OSI-RDA as
well as supplying the needed application interfaces: the SQL Access Group.
Both efforts are described below. I am active on the ANSI RDA committee
(ANSI X3H2.1) as well as the SQL Access Group.
ISO OSI RDA
First, there is an ISO standard being developed to address remote database
access (RDA). The RDA standard (9579 DP) is part of the OSI Reference
Model and it resides in layer 7 (application layer). The ANSI committee
that takes US positions to the ISO RDA meetings is ANSI X3H2.1 (RDA).
The purpose of the RDA standard is to solve the problem of remote hetero-
geneous database access. RDA is based on the client/server model of
interaction. As with the other OSI standards, RDA does not attempt to
define application programming interfaces (API's). Instead, it concen-
trates on specifying the services, message formats, and protocols needed
for this type of interoperation.
The RDA standard is comprised of two logical parts: Generic RDA and RDA
Specializations. The Generic RDA standard specifies the operations and
behaviors that are applicable to virtually all database languages (open
resource, close resource, execute DBL, etc). RDA Specializations then
further clarify the operations and behaviors for a specific database
language. Currently, there is only one RDA Specialization being actively
developed and it is the SQL Specialization. However, work may have started
on an ISO IRDS Specialization as well. The committee that I work on han-
dles both Generic RDA and the SQL Specialization.
The SQL Access Group
The SQL Access Group is dedicated to advancing the SQL2 and RDA standards
as quickly as possible, i.e. to accelerate the work being done in the
standards bodies (ANSI and ISO) with respect to remote SQL processing. Its
goal is to have working prototypes, interoperability demonstrations, and
specifications that include both standards.
There are two technical groups within SQL Access. The API group (Applica-
tion Programming Interfaces) is concerned with the changes that are needed
to the SQL database language in order to support remote SQL access. This
group drives needed changes through the ANSI SQL committee. The FAP group
(Formats and Protocols) works on the communication issues. The FAP group
concentrates on advancing the work being done in the OSI RDA (Remote Data-
base Access) committee.
