Why you should learn SQL?
SQL or “Sequel” as some other literature and developer communities
call it is a very old language that is widely used by developers or data experts in communicating and working on databases. It was developed from the postulation of Dr E.F Codd in 1970 about redesigning the way data is being stored. In his paper, Codd postulated that data should be stored in relations — tables (in rows and columns).
This idea brought about the emergence of Databases and SQL as a language to use for communicating with the databases. As a language, it has its place established as a language among developers and experts who would be working with data.

So, why should you learn SQL as a Database Administrator or a Data Scientist?
- SQL is used everywhere.
The language supports anything that has to do with data. This includes application development, business processes and so on.
