Abstract
To get more meaning of incomplete information, a predicate way is proposed to represent the nulls. The concepts of functional and multivalued dependencies are extended in the environment which allows nulls in a database relation. The inference rules which can be applied to the extended dependencies are investigated. Finally it is shown that the rules are complete for the family of extended functional and multivalued dependencies.
