SQL Vs NoSQL

Welcome back! I’ve been making a ton of articles going into detail of the programming languages used at top companies, a lot of comments wanted me to understand the differences between these two query languages, so let’s talk about what the main differences are between these languages. First off, NoSQL is not a variation of SQL, they both live independent to one another.

What is the difference?

The main difference between these two languages is: SQL databases are relational where NoSQL databases are built non-relational, what does this mean? Well, a relational database stores data which are related to one another, a good example of this is found on Omnisci.com:
