Functional Dependency is the starting point of normalization. It exists when a relation between two attributes allow you to determine the corresponding attribute's value uniquely. The functional dependency is also known as database dependency and defines as the relationship which occurs when one attribu...
BCNF stands for Boyce-Codd Normal Form is a form of normalization. It is an advanced version of the 3 NF (Third Normal form). A table is in BCNF is there are no non-trivial functional dependencies except the superset of a candidate key. So for a functional dependency, X → Y, X has...

Why do we need Normalization? The main reason for normalizing the relations is removing these anomalies. Failure to eliminate anomalies leads to data redundancy and can cause data integrity and other problems as the database grows. Normalization consists of a series of guidelines that helps to guid...
We should be able to delete one type of data or one record without having impacts on other records we don’t want to delete. What Are The Normal Forms? The process of normalization involves applying rules to a set of data. Each of these rules transforms the data to a certain structure,...
