As the world becomes more data-driven, SQL is increasingly moving from a "nice to have" skill to a first class requirement for disciplines like Data Science, Machine Learning and Business Intelligence. Here's a free resource for learning SQL right in your browser.

With the fight between Python and Java on which will rank top of the TIOBE index, it is easy to forget that are other contenders filling the top 10. And one of those is SQL, moving up into 10th place this July, as reported in "Python Trending To Top Spot In TIOBE Index".

SQL used to be considered an important but secondary skill that complemented the prime skill of knowing a true programming language like Java. That is, until recently, you could get a job that required Java and not SQL, but not the other way around. Possessing both of them was ideal and that would be reflect in the salary as well. But, as HackerRank's recent University Recruitment report emphasizes, knowing SQL as well as Java or Python is an increasingly recognized as essential by both job seekers and hiring managers. 

SQL has certainly proved very resilient in time, currently spanning several decades since its inception. Inherent value aside,that it remained ever relevant has to also do with its continuous revamps in the form of the ongoing ANSI SQL standards which are refreshing the language. This demonstrates to the cool kids that a technology being old doesn't also mean that it is irrelevant.
