| 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. |
