About the Course
SQL is the foundation of any Data science study. Even after the advent of NoSQL, most of the applications still use SQL to manipulate and manage the data.
A strong knowledge in SQL is required for a person who is willing to start a career in Application Programming, Business Intelligence, Analytics or in a cloud based software product space.
