WebDatabase normalization or database normalisation (see spelling differences) is the process of 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 first proposed by British computer scientist Edgar F. Codd as part of his relational model . WebSo, Normalization means split the tables into small tables which will contain less number of attributes in such a way that table design must not contain any problem of inserting, deleting, updating anomalies and guarantees no redundancy. To do normalization we use concept of “Functional dependency” and “Candidate keys”.
