| Goal | This query generates a list of all foreign key constraints that are defined with the ON UPDATE CASCADE action. This list must be manually audited to enforce the design principle that this action should be applied exclusively to relationships involving mutable, natural keys. Any instance found referencing an immutable surrogate key should be considered a design flaw and remediated. |
