To understand what is Partial Dependency and how you can normalize a table to 2nd normal form, jump to the DBMS Second Normal Form tutorial.3. 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...
The most commonly used types of normalization in SQL are the First Normal Form (1NF), Second Normal Form (2NF), Third Normal Form (3NF), Fourth Normal Form (4NF), and Boyce-Codd Normal Form.First Normal Form (1NF)1NF ensures that each column in a table contains atomic (indivisible) ...
BCNF is considered to be the stronger than 3NF. The relation R to be in BCNF must be in3NF. And wherever anon-trivial functional dependency A -> Bholds in relation R, thenAmust be asuperkeyof relation R. As we know, Super key is a key which has a single attribute or set of attr...
