A Data Scientist Will Never Be Able To Escape SQL

For a language that was developed in the 1970s, SQL (Structured Query Language) is one of the most important skills you will need in your journey to become a data scientist.

In fact, together with R and Python, SQL forms the celebrated trio of data science programming languages that are most used by data science professionals.

And if these are not enough to convince you to learn SQL, consider this: mastering SQL, which is the bread and butter of data science, opens the doors to plenty of job opportunities.
