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:
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
“There used to be a thing or a commodity we put great store by. It was called the People. Find out where the People have gone. I don’t mean the square-eyed toothpaste-and-hair-dye people or the new-car-or-bust people, or the success-and-coronary people. Maybe they never existed, but if there ever were the People, that’s the commodity the Declaration was talking about, and Mr. Lincoln.”
—John Steinbeck (1902–1968)
