1NF,2NF,3NF and BCNF in Database Normalization

Boyce and Codd Normal Form (BCNF) Boyce and Codd Normal Form is a higher version of the Third Normal form.This form deals with certain type of anomaly that is not handled by 3NF.A 3NF table which does not have multiple overlapping candidate keys is said to be in BCNF.For a table to be in BCNF,following conditions must be satisfied:1NF,2NF,3NF and BCNF in Database Normalization Database Normalization .Database Normalization; First Normal Form (1NF) Second Normal Form (2NF) Third Normal Form (3NF) Boyce-Codd Normal Form (BCNF) Fourth Normal Form (4NF) Fifth Normal Form (5NF) SQL Concept .SQL Introduction; DDL Command.Create query; Alter query; Truncate,Drop and Rename query; DML Command.INSERT command; UPDATE command;1NF,2NF,3NF and BCNF in Database Normalization1NF,2NF,3NF and BCNF in Database Normalization DBMS Tutorial.Normalization is a design technique that is widely used as a guide in designing relation database.Tutorial for First Normal Form,Second Normal Form,Third Normal Form,BCNF and Fourth Normal Form.Toggle navigationScanftree.
