Normal form information

Normal form may refer to: Normal form (databases) Normal form (game theory) Canonical form Normal form (dynamical systems) Hesse normal form Normal form...

Third normal form (3NF) is a database schema design approach for relational databases which uses normalizing principles to reduce the duplication of data...

In Boolean logic, a formula is in conjunctive normal form (CNF) or clausal normal form if it is a conjunction of one or more clauses, where a clause is...

First normal form (1NF) is a property of a relation in a relational database. A relation is in first normal form if and only if no attribute domain has...

linear algebra, a Jordan normal form, also known as a Jordan canonical form (JCF), is an upper triangular matrix of a particular form called a Jordan matrix...

G, is said to be in Chomsky normal form (first described by Noam Chomsky) if all of its production rules are of the form: A → BC,   or A → a,   or S →...

Fourth normal form (4NF) is a normal form used in database normalization. Introduced by Ronald Fagin in 1977, 4NF is the next level of normalization after...

Fifth normal form (5NF), also known as projection–join normal form (PJ/NF), is a level of database normalization designed to remove redundancy in relational...

Second normal form (2NF), in database normalization, is a normal form that is met if each attribute that is not part of the primary key depends on all...

Sixth normal form (6NF) is a normal form used in relational database normalization which extends the relational algebra and generalizes relational operators...

structuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. It was...

normal form if it is in prenex normal form with only universal first-order quantifiers. Every first-order formula may be converted into Skolem normal...

In boolean logic, a disjunctive normal form (DNF) is a canonical normal form of a logical formula consisting of a disjunction of conjunctions; it can also...

disjunctive normal form (CDNF) or minterm canonical form, and its dual, the canonical conjunctive normal form (CCNF) or maxterm canonical form. Other canonical...

with the normal forms in propositional logic (e.g. disjunctive normal form or conjunctive normal form), it provides a canonical normal form useful in...

algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers Z. Just as reduced echelon form can be used to solve...

In formal language theory, a context-free grammar is in Greibach normal form (GNF) if the right-hand sides of all production rules start with a terminal...

language theory, a noncontracting grammar is in Kuroda normal form if all production rules are of the form: AB → CD or A → BC or A → B or A → a where A, B,...

algebra, the Frobenius normal form or rational canonical form of a square matrix A with entries in a field F is a canonical form for matrices obtained...

lambda calculus, a term is in beta normal form if no beta reduction is possible. A term is in beta-eta normal form if neither a beta reduction nor an...

In Boolean algebra, the algebraic normal form (ANF), ring sum normal form (RSNF or RNF), Zhegalkin normal form, or Reed–Muller expansion is a way of writing...

In mathematics and computer science, a canonical, normal, or standard form of a mathematical object is a standard way of presenting that object as a mathematical...

In mathematics, the Smith normal form (sometimes abbreviated SNF) is a normal form that can be defined for any matrix (not necessarily square) with entries...

The Hesse normal form named after Otto Hesse, is an equation used in analytic geometry, and describes a line in R2{\displaystyle \mathbb {R} ^{2}} or...

In mathematical logic, a formula is in negation normal form (NNF) if the negation operator ( ¬ {\displaystyle \lnot } , not) is only applied to variables...
