N2 - Here in this paper, we formally define fuzzy multivalued dependencies on a chosen fuzzy database model. Since fuctional dependencies have already been extended for fuzzy database models, we only deal with an important integrity constraints, namely multivalued dependencies (MVDs), for the fuzzy relational database introduced by Buckles and Petry. We show that the defined fuzzy MVDs (FMVDs) are consistent and reduce to the classic MVDs when they involve precise attribute values. We also give some examples to show how the integrity constraints imposed by the FMVDs are forced whenever a tuple is to be inserted or to be modified.
