Answer 1

The problem is coming from this:
CONSTRAINT `fk_users_has_ratings_businesses1`
FOREIGN KEY (`business_id`)
REFERENCES `yuldi`.`businesses` (`id`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
The record you're trying to insert / update - probably user_ratings - is foreign keyed to the businesses table; you can't create a user_ratings record without a business_id, and that business_id must actually exist as an id in the businesses table.
