The Integrated Data Store ( IDS ) is one of the first created and most widely used network databases known for its high performance.
IDS was created in the 1960s by the General Electric computer division (this division was sold to Honeywell in 1970 and became known as Honeywell Information Systems ) under the direction of Charles Bachmann , who received the Turing Award for its creation in 1973. [one]
A detailed specification for IDS was created in January 1962. In May, Bachmann introduced the details of the future system to GE customers. According to Bachmann's own recollections, the prototype system was completed in December 1962. [2] . The program was released in 1964. She worked on a GE-235 computer, with which it was sold. It was later ported to GE 400 and 600 series computers. It worked on top of the proprietary GCOS operating system.
By 1965, an IDS version for Weyerhaeuser Lumber was released, allowing it to work with it through a network. [3]
In 1970, General Electric sold its computer business to Honeywell, along with all intellectual property. Honeywell continued to develop IDS by launching a version of Honeywell IDS / II (or Honeywell IDS-2) in 1975 [4] [5] .
In 1991, the Honeywell computer division was sold to the French computer company Groupe Bull , and IDS began to be sold under the name Bull IDS / II (or Bull IDS-2) [6] .
IDS was not easy to use and it was difficult to create applications on its basis. The fact is that in IDS, the emphasis was on performance on the meager hardware that was available at the time. Currently, IDS is used in the British Telecom CSS project, which shows excellent performance results on terabyte datasets. [7]
Interesting Facts
- The ideas put forward by Bachmann in IDS were used by CODASYL to create the official standard for a network data model.
- One copy of IDS was sold with a GE computer to BF Goodrich Chemical Division. To their surprise, the developers of the company learned that they can change the IDS source code at their discretion, without paying GE any payments. So another IDMS network database was created — the first network database written for IBM S / 360 mainframes . The sale and development of IDMS was undertaken by the private enterprise Cullinet . In 1981, Charles Bachmann joined this company and, under his leadership, IDMS developed further.
