Multics Relational Data Store

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)

    I see now that we store him up
    year after year, old suicides
    and I know at the news of your death,
    a terrible taste for it, like salt.
    Anne Sexton (1928–1974)
