Nov 3, 2016 · Normalization is a process used to organize data in a database. It involves breaking tables into smaller, more manageable pieces to reduce data redundancy and improve data integrity. There are several normal forms including 1NF, 2NF, 3NF, BCNF, 4NF and 5NF.
Nov 3, 2016 · Database normalization • Normalization is the process of reorganizing data in a database so that it meets two basic requirements: i. There is no redundancy of data. ii. Data dependencies are logical. • Normalization usually involves dividing a database into two or more tables and defining relationships between the tables.

Normalization is a technique for producing a set of relations with desirable properties, given the data requirements of an enterprise. The process of normalization is a formal method that identifies relations based on their primary or candidate keys and the functional dependencies among their attributes.

Normalization is essentially a two step process that puts data into tabular form by removing repeating groups and then removes duplicated data from the relational tables. Normalization theory is based on the concepts of normal forms. A relational table is said to be in a particular normal form if it satisfied a certain set of constraints.
Apr 8, 2023 · Presentation on Normalization.pptx. The document provides an overview of database normalization through 6 levels: 1) First normal form (1NF) removes repeating groups from tables. 2) Second normal form (2NF) removes partial dependencies from tables that are in 1NF.
