According to a recent report from Burning Glass SQL was the most requested tech skill in open jobs posted between February and March 2020. Businesses are collecting ever-increasing volumes of data and the question of how to derive value from this asset is becoming something of a business obsession.
We’re entering a new world in which data may be more important than software.” , Tim O’Reilly, founder, O’Reilly Media
The vast majority of enterprise data is still stored as rows and columns in databases and SQL (Structured Query Language) is the language that enables a business to extract, transform and load this data. SQL is, therefore, the very foundation on which any value-adding data products are developed.
I am in the middle of running an online SQL course for complete beginners. The program that I have put together uses existing free online resources that I coach my students through via weekly video calls. In this article, I wanted to share with you the five best free resources that we have used so far to learn SQL during the course.
