Referential integrity constraints specify the rules governing the relationships between entity types in a database. These constraints ensure that the values in one table's foreign key field match the values in another table's primary key field, thus maintaining the integrity of the relationship between the two tables. Triggering operations specify actions to be taken when certain events occur, entity integrity ensures that each entity in a table has a unique primary key, and domains specify the set of valid values for a field in the database.
