The third normal form — or 3NF — is part of a set of concepts for database normalization that also includes first normal form (1NF) and second normal form (2NF). Advertisements These ideas are traced back to data scientist Edgar Codd and his work in the 1970s — working for IBM, Co...
Second Normal Form expects a table to be in first normal form and not have partial dependency in case of composite primary key for a table. In this tutorial, we will learn what partial dependency is and how to remove it for second Normal form.
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.
