Why should you care about SQL?


The SQL language has been a data querying standard for many, many years. This article describes the history of the language and its origins.

Structured Query Language SQL

The advent of new data architectures to the mainstream market seemed to threaten the future of the SQL. The REST APIs, custom querying languages and data interfaces seemed to gain momentum. 

Yet, pretty much every leading NoSQL technology is associated with a community requesting, or implementing an SQL interface to it. For example Microsoft implemented an SQL interface to their flagship NoSQL/Hybrid product, CosmosDB.

Why? Because most data professionals are familiar with the syntax of SELECT statements, WHERE clauses, JOINs and GROUP BYs. It is easier to move to new project knowing that you will still be able to use the data without learning completely new syntax. I call it a throw-away syntax, as it mostly applies to one technology only.
