Welcome to the Database Interoperability Web page.
The Distributed Relational Database Architecture (DRDA) Version 4 technical standard (April 2007) is available from The Open Group's online bookstore:
It supersedes the DRDA V3 technical standard (C043, C044, C045) which was published in January 2004.
Revisions to DRDA V3 Technical Standard
The call to update the DRDA V3 technical standard primarily involved adding support for a number of ANSI SQL Datatypes, including BOOLEAN, NCHAR, NCLOB, NVARCHAR, and XML. This work also offered opportunity to apply other desirable updates.
Update process - Fasttrack by IBM
The update project was led by IBM, who after a period of consultation with qualified parties who had previously declared their interest in contributing updates and review comments, submitted the updated specification to The Open Group's 'Fasttrack Review' process. Successful progress through this Fasttrack process resulted in publication by The Open Group of the updated DRDA version 4 technical standard, which superseded the January 2004 DRDA v3 technical standard.
Background
Over a 5-year period ending in December 2003, The Open Group hosted a Database Interoperability Managed Consortium (DBIOP), whose members developed the DRDA 3-volume specification, which was approved and published by The Open Group as the Distributed Relational Database Architecture (DRDA) Version 3. The DBIOP Consortium members, having completed their stated objectives, then closed the DBIOP Managed Consortium. More information on the origins and evolution of the DBIOP Managed Consortium to develop the January 2004 DRDA standard is available here.
Then in mid-2006, a number of database vendors approached The Open Group with proposals to update the DRDA V3 technical standard, to add more datatypes and make additional updates which would support the significant open source development work that they were all enagaged in supporting. These vendors included IBM, Microsoft, Rocket Software, Starquest Ventures, and Sun Microsystems. As a Platinum member of The Open Group, IBM co-ordinated contributions from these participating vendors, and submitted an updated specification into The Open Group's fasttrack process. The formal fasttrack review was duly completed within the deterministic timeframe it defines, resulting in a successful outcome. Accordingly the Governing Board of The Open Group approved its publication as the Distributed Relational Database Architecture (DRDA) Version 4 technical standard, and it was duly published in April 2007.
