Cardinality Constraints
Explore how to apply cardinality constraints to multi-valued properties in JavaScript. Understand minimum and maximum limits for data validation, learn UML multiplicity concepts, and see practical examples for enforcing these constraints in front-end web applications.

A cardinality constraint requires that the cardinality of a multi-valued property’s value set is not less than a given minimum cardinality or not greater than a given maximum cardinality.
Cardinality constraints in UML
In UML, cardinality constraints are called multiplicity constraints, and minimum and maximum cardinalities are expressed with the lower bound ...
