Rezumat

In this paper, based on equivalence classes of attributes there are formulated necessary and suffcient conditions that constrain a database schema to be in the second, third or Boyce-Codd normal forms. These conditions offer a polynomial complexity for the testing algorithms of the normalizations level.
