Hands-On Data Modeling: Convert ERD to 3NF and Star Schema

In this video, I have explained in a very simple language what is a Data Model and various components in it. I have explained Entity Relationship Diagram (ERD) and how to build one. Then I have explained Normalisation and also shared how to convert ERD into 3NF form. Moreover I have explained dimensional modeling and how to convert 3NF table into Star Schema.
