What is SQL and why should I care about learning it?
Like it or not, Data is everywhere. From your Instagram feed to the supermarket shelves, without data and data management software, it would all fall apart. Databases hold all this data and, in order to manipulate it, we need a language to help us to "talk" to the database. That language is called SQL and it still sits in the top 10 programming languages in the world despite being invented in 1970!
In this course, you'll learn to create and manipulate databases with a mix of SQL and Python.
