Unisys DMSII (original) (raw)

The Unisys Data Management System II (DMSII) is a database system originally created by the Burroughs Corporation in 1972. It was available on the Burroughs (later Unisys) Small (B1000), Medium (4000, V Series) and Large System (5000, 6000, 7000) product lines. The later, A Series, Clearpath, Libra product lines support it and in recent releases of Unisys Clearpath software it has been renamed as the Enterprise Database Server for ClearPath MCP. The original DMS II used a network model. It originally competed with IBM's IMS and CICS products and predated the popularity of relational databases.
