Summary
We study the interrelation between various versions of the complementation rule and other inference rules for multivalued dependencies in database relations. In particular we settle two open questions of [1] concerning the derivability of inference rules for Boolean operations on the right side of multivalued dependencies. Furthermore we prove that there is a trade-off between the complementation rule and the augmentation rule.
