Introduction to Normalization.Normalization is a process of organizing the data in the database.; It is a systematic approach of decomposing tables to eliminate data redundancy.It was developed by E.F.Codd.; Normalization is a multi-step process that puts the data into a tabular form by removing the duplicate data from the relation tables.Database Normalization - W3SchoolsThe words normalization and normal form refer to the structure of a database.Normalization was developed by IBM researcher E.F.Codd In the 1970s.Normalization increases clarity in organizing data in Databases.Normalization of a Database is achieved by following a set of rules called 'forms' in creating the database.Database Normalization RulesDBMS 1NF - javatpointFirst Normal Form (1NF) A relation will be 1NF if it contains an atomic value.It states that an attribute of a table cannot hold multiple values.It must hold only single-valued attribute.First normal form disallows the multi-valued attribute,composite attribute,and their combinations.
