The Multics Relational Data Store, or MRDS for short, was the first commercial
relational database management system. It was written in
PL/1 by
Honeywell for the
Multics
operating system and first sold in June 1976. Unlike the
SQL systems that emerged in the late 1970s and early 80s, MRDS used a command language only for basic data manipulation, equivalent to the SELECT
or UPDATE
statements in SQL. Other operations, like creating a new database, or general file management, required the use of a separate command program.
