The Multics Relational Data Store, or MRDS for short, was the first commercial relational database management system. It was written 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 80's, 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.
Famous quotes containing the words data and/or store:
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“I keep thinking that what I need
to do is buy my leg back.
Surely it is for sale somewhere,
poor broken tool, poor ornament.
It might be in a store somewhere beside a lady’s scarf.”
—Anne Sexton (1928–1974)
