Description
A few years ago, The Economist published an article in which they stated that data has replaced oil as the most valuable resource in the world.
You may or may not agree, but the truth is, millions of businesses all around the work run on data. All the strategies, operations, and decisions – everything is based on the conclusions made after collecting and analyzing massive amounts of data. To be able to do that, companies use large databases. The most popular ones are relational databases – and to be able to work with them, you need to know SQL.
