public class FKConstraint
A FKConstraint
represents a Foreign Key Constraint.
A foreign key constraint requires values in the constrained table to match
values in another table.
An FKConstraint contains a reference to a UniqueConstraint. This referenced constraint determines the valid values for the columns constrained.
