Data constraints are limitations on data values:

Domain constraint - Column values must be in a given set of specific values.

Range constraint - Column values must be within a given range of values.

Intrarelation constraint - Column values are limited by comparison to values in other columns in the same table.

Interrelation constraint - Column values are limited by comparison to values in other columns in other tables [Referential integrity constraints on foreign keys].
