Unisys DMSII Online Test

Unisys Data Management System II (DMSII) is a database system. The Burroughs Corporation originally created this database system in 1972, and it mainly provided an ISAM (indexed sequential access method) model for data access, transaction isolation, and database-recovery capabilities.

Unisys DMSII supported both hierarchical and relational models, a data set that could be disjointed or embedded.
