Abstract
In this paper, we show that some Codd third normal form relations
may contain "superfluous" attributes because the definitions of
transitive dependency and prime attribute are inadequate when applied
to sets of relations. To correct this, an improved third normal form
is defined and an algorithm is given to construct a set of relations
from a given set of functional dependencies in such a way that the
superfluous attributes are guaranteed to be removed. This new normal
form is compared with other existing definitions of third normal form,
and the deletion normalization method proposed is shown to subsume
the decomposition method of normalization.
