normal form
31fifth normal form — noun A stage in the normalization of a relational database in which a database is in fourth normal form and every join dependency is implied by the candidate keys. See Also: first normal form …
32second normal form — noun A stage in the normalization of a relational database in which it is in first normal form and every non key attribute is dependent upon the entire primary key. See Also: first normal form …
33Boyce-Codd normal form — noun A stage in the normalization of a relational database in which a database is in third normal form and all determinants are candidate keys. See Also: first normal form, second normal form, fourth normal form, fift …
34third normal form — noun A stage in the normalization of a relational database in which a database is in second normal form and all non key attributes are mutually independent (no transient dependencies.) See Also …
35fourth normal form — noun A stage in the normalization of a relational database in which a database is in Boyce Codd normal form and all multi valued dependencies are functional dependencies. See Also: first normal form, second normal form, third normal form …
36first normal form — noun A stage in the normalization of a relational database in which repeating groups and attributes have been eliminated by putting each into a separate table connected by a primary key foreign key relationship. See Also: second normal form …
37Algebraic normal form — In Boolean logic, the algebraic normal form (ANF) is a method of standardizing and normalizing logical formulas. As a normal form, it can be used in automated theorem proving (ATP), but is more commonly used in the design of cryptographic random… …
38Fifth normal form — (5NF), also known as Project join normal form (PJ/NF) is a level of database normalization, designed to reduce redundancy in relational databases recording multi valued facts by isolating semantically related multiple relationships. A table is… …
39Skolem normal form — A formula is in Skolem normal form if it is in prenex normal form, and all the existential quantifiers come first. There is an effective procedure producing, for any formula, one in Skolem normal form that is valid if and only if the original is… …
40Hermite normal form — In linear algebra, the Hermite normal form is a special form of reduced echelon form over the integers mathbb{Z}. Specifically, a matrix M over mathbb{Z} is said to be in Hermite normal form (often abbreviated HNF) if* It is upper triangular *… …
