Remote Data Access

Remote database access (RDA) is a protocol standard for database access. Despite early efforts to develop proof of concept implementations of RDA for major commercial RDBMSs (including Oracle, Rdb, NonStop SQL and Teradata), this standard has been largely ignored by commercial database vendors.

RDA describes the connection of a database client to a database server. It includes features for

  • Communicating database operations and parameters from the client to the server,
  • In return, transporting result data from the server to the client,
  • Database transaction management.
  • Exchange of information.

RDA is an application-level protocol, inasmuch that it builds on an existing network connection between client and server. In the case of TCP/IP connections, RFC 1066 is used for implementing RDA.

RDA was published in 1993, as a combined standard of ANSI, (International Organization for Standardization) ISO and (International Electrotechnical Commission ) IEC. The standards definition comprises two parts:

  • ANSI/ISO/IEC 9579-1:1993
  • ANSI/ISO/IEC 9579-2:1993
