The model for database management is a database model based on first-order predicate logic.

Answer: relational

Explanation:
The Relational model describes a database as a collection of predicates over a finite set
of predicate variables, describing
constraints on the possible values and combinations of values. The content of the database at any
given time is a finite (logical) model of the
database, i.e., a set of relations, one per predicate variable, such that all predicates are satisfied. A
request for information from the database
or a database query is also a predicate.
