Web in computer science, administrative normal form (abbreviated anf) is a canonical form of programs, which was introduced by flanagan et al 1993 to serve as an intermediate representation in functional compilers to make subsequent transformations to machine code more direct. This includes creating tables and establishing relationships between those tables according to rules designed both to protect the data and to make the database more flexible by eliminating redundancy and inconsistent dependency.

Web first normal form (1nf) is a property of a relation in a relational database. Web the normal form (sf) is called the sylvester form, or sometimes the companion matrix.

In this paper, we build rational normal form with exact global control of small divisors. What is the purpose of normalization? It is also used to eliminate undesirable characteristics like insertion, update, and deletion anomalies. There are several levels of normalization, each with its own set of guidelines, known as normal forms. Basic form covers these 11 “perils” or causes of loss: Fourth normal form (4nf) 6.
