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.
Despite its 40-year legacy, SQL is very much alive and well, and is used by big and small companies alike to tackle challenging analytics problems and answer questions to improve business processes, operations and sales ROI.
