Class: check_foreign_keys  - X-Ref

This class will look for data in the database that violates the foreign
key definitions found in the XMLDB definitions.

Note that by default, this check does not complain about foreign key
violations from, say, a userid column defined as NOT NULL DEFAULT '0'.
Each 0 in that column will violate the foreign key, but we ignore them.
If you want a strict check performed, then add &strict=1 to the URL.
