Abstract
Databases may enforce foreign key constraints for efficient materialized view updates. A materialized view may be created for a database. Updates to the database may be received and performed according to a foreign key constraint enforced with respect to the updates. An update to the materialized view may be performed to make the materialized view consistent with the updates to the database. Performance of a join operation to update the materialized view that would return a result violating the foreign key constraint may be excluded from the update to the materialized view.
