Rezumat | ||||||
In this paper there is proposed a method of partition the
attributes of relation scheme in equivalence classes and in nonredundant equivalence classes. Several properties of these equivalence classes are proved. Their properties serve as the basis for
an algorithm with a polynomial complexity, which determines the
prime attributes of a database schema. |

Cuvinte-cheie Relation scheme, functional dependencies, equivalence classes, prime attributes, polynomial complexity tasks. |
