What is a constraint in relational databases?from c-sharpcorner.com
Relational databases enforce data integrity with constraints or rules applied to a column that defines what action to take when data in a related column or row is changed. In ADO.NET there are two types of constraints; ForeignKeyConstraint and UniqueConstraint. A constraint is a rule used to maintain the integrity of the data in the DataTable. For example, when we delete a value that is used in one or more related tables, a ForeignKeyConstraint determines whether the values in the related tables are also deleted, set to null values, set to default values, or whether no action occurs. A UniqueConstraint, on the other hand, simply ensures that all values within a particular table are unique. A base Constraint constructor is not used. Primary or unique key constraints are created using the UniqueConstraint constructor, and foreign key constraints are created using the ForeignKeyConstraint constructor.
