First Normal form is the first step of normalization. In this tutorial we will have an example to explain how you can update you table to follow the First Normal Form or 1NF. This is the beginning of Database Normalization process.
• 3NF: Eliminate Columns Not Dependent On Primary KeyIf attributes do not contribute to a description of the key, then remove them to a separate table. All attributes must be directly dependent on the primary key.• BCNF: Boyce-Codd Normal FormIf there are non-trivial dependencies between...
update, and deletion of data. There is the First Normal Form (1NF), Second Normal Form (2NF), Third Normal Form (3NF), Boyce-Codd Normal Form (BCNF), Fourth Normal Form (4NF), and Fifth Normal Form
