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)
“Every third year you shall bring out the full tithe of your produce for that year, and store it within your towns; the Levites, because they have no allotment or inheritance with you, as well as the resident aliens, the orphans, and the widows in your towns, may come and eat their fill so that the LORD your God may bless you in all the work that you undertake.”
—Bible: Hebrew, Deuteronomy 14:28,29.
