IMS @ Conception
October-December 2009 (vol. 31 no. 4)
pp. 62-65

Database and data communication software systems extend a computer's operational environment to reduce programming effort and provide a standardized face for production operations. Developed in the mid-1960s, Information Management System/360 began as a joint project to enable Rockwell Space Division's transition to System/360 computers. This project resulted in one of the first of this class of systems and one of the most successful.

1. For more information on Uri Berman, see his essay, "The Birth of IMS/360 by Berman," at http://www.softwarehistory.org/pdfxx-BirthofIMS.pdf .
2. The IMS/360 was originally called the Information Control System (ICS), but the name change occurred early in the project development effort.
3. The master copy of the original DL/1 manual now resides in the Computer History Museum.

5. Unlike the executives, architects, and designers who successfully conceive and complete programming packages of note, those who install and solve the initial problems of a big offering rarely receive awards. One deserving mention is Bill Grafton, the installations chief for the first IMS installation in 1968. For the story of putting it all together, see W.P. Grafton, "IMS: Past, Present, Future," Datamation, Sept. 1983.
