Uri Berman describes how he developed general-purpose software for Rockwell’s Space Division that supported disk operations and separated the applications programmer from the details. When that software, which included the initial version of Data Language/One (DL/1), was moved from the IBM 7010 to the IBM System/360, he and his colleagues developed a standard way to state data definitions and developed the new software to IBM Type 2 standards. The resulting package was called IMS/360 (Information Management System/360) and contained DL/I. At its 20th anniversary in 1988, IBM stated that IMS was being used in 7,000 installations worldwide.
