A Correct answer
Explanation

DMS (Data Management System), originally IDMS (Integrated Data Store), is a network database model. In network model databases, records are connected in a many-to-many relationship graph, unlike hierarchical databases which use tree structures.

AI explanation

Network is correct. DMS (as in DMS-1100, Sperry/Univac's implementation, descended from GE's early Data Management System work by Charles Bachman) was one of the classic CODASYL-style database systems built on the network data model, where records are connected via owner-member 'sets' (linked-list style relationships) rather than tables or hierarchies. It predates and helped shape the CODASYL DBTG network model standard. It is not hierarchical (that's the IMS/tree-structured lineage) nor relational (Codd's tabular model came later, in the 1970s), so 'Hierarchical', 'Relational', and 'None of these' are all wrong.
