    • Database Normalization With Examples. Database Normalization Example can be easily understood with the help of a case study. Assume, a video library maintains a database of movies rented out.
    • BCNF (Boyce-Codd Normal Form)
    • 4NF (Fourth Normal Form) Rules. If no database table instance contains two or more, independent and multivalued data describing the relevant entity, then it is in 4 Normal Form.
    • 5NF (Fifth Normal Form) Rules. A table is in 5 Normal Form only if it is in 4NF and it cannot be decomposed into any number of smaller tables without loss of data.

    • First Normal Form (1NF) For a table to be in the First Normal Form, it should follow the following 4 rules: It should only have single(atomic) valued attributes/columns.
    • Second Normal Form (2NF) For a table to be in the Second Normal Form, It should be in the First Normal form. And, it should not have Partial Dependency.
    • Third Normal Form (3NF) A table is said to be in the Third Normal Form when, It satisfies the First Normal Form and the Second Normal form. And, it doesn't have Transitive Dependency.
    • Boyce-Codd Normal Form (BCNF) Boyce and Codd Normal Form is a higher version of the Third Normal Form. This form deals with a certain type of anomaly that is not handled by 3NF.
