Axiomatics for multivalued dependencies in table databases and axiomatics for functional and multivalued dependencies are reviewed; the completeness of these axiomatics is established in terms of coincidence of syntactic and semantic consequence relations; the completeness criteria for these axiomatic systems are formulated in terms of cardinalities (1) of the universal domain
D
, which is considering in interpretations, and (2) the scheme
R
, which is a parameter of all constructions, because only the tables which attributes belong to this scheme
R
are considering.
The results obtained in this paper and developed mathematical technique can be used for algorithmic support of normalization in table databases.
