Specifies the application programming interface for X/Open-compliant relational database management systems. This API standard information is closely based on the International Standard for the Database Lan guage (SQL), ISO 9075:1992, but includes some extensions based on current implementations. This document encompasses features required by NIST FIPS 127-2, also known as "Transitional SQL." Database developers concerned about X/Open comp liance.

A collaborative effort between X/Open and the SQL Access Group, this book offers the SQL definitions specifying the application programming interface (API) for X/Open-compliant database management systems, and the RDA specification. It includes some SQL extensions reflecting the capabilities of current implementations. The RDA specification defines uses of the message fields and other implementation information, such as sequencing and optional features, and it shows how SQL statements map to the Remote Database Access (RDA) protocol.
