Irreducible Function Depending Set
A functional depending set S is irreducible if the set has the following three properties:
- Each right set of a functional dependency of S contains only one attribute.
- Each left set of a functional dependency of S is irreducible. It means that reducing any one attribute from left set will change the content of S (S will lose some information).
- Reducing any functional dependency will change the content of S.
Sets of Functional Dependencies(FD) with these properties are also called canonical or minimal.

Famous quotes containing the words irreducible, function, depending and/or set:
“If an irreducible distinction between theatre and cinema does exist, it may be this: Theatre is confined to a logical or continuous use of space. Cinema ... has access to an alogical or discontinuous use of space.”
—Susan Sontag (b. 1933)
“No one, however powerful and successful, can function as an adult if his parents are not satisfied with him.”
—Frank Pittman (20th century)
“So that the life of a writer, whatever he might fancy to the contrary, was not so much a state of composition, as a state of warfare; and his probation in it, precisely that of any other man militant upon earth,—both depending alike, not half so much upon the degrees of his WIT—as his RESISTANCE.”
—Laurence Sterne (1713–1768)
“One might get the impression that I recommend a new methodology which replaces induction by counterinduction and uses a multiplicity of theories, metaphysical views, fairy tales, instead of the customary pair theory/observation. This impression would certainly be mistaken. My intention is not to replace one set of general rules by another such set: my intention is rather to convince the reader that all methodologies, even the most obvious ones, have their limits.”
—Paul Feyerabend (1924–1994)
