    Concept of super key was very well explained in first 2:30 minutes and I will remember it for lifetime now , but he really explained the mathematical approach of it so well that I cant skip that and watch till end. This series is helping me to learn SQL part for my data analytics, Kudos to you and your hard work !!!
