What is SQL?

As my first post, I shall start with the basics.

What is SQL? The bread and butter of the majority of data jobs.

SQL stands for Structured Query Language.

SQL is the most common language used to extract and manipulate data from a Relational Database Management System (RDBMS). Examples of RDBMS: Microsoft SQL Server, PostgreSQL, Oracle and MySQL.

Most companies have some or all of their data stored in a RDBMS.

This is why SQL is important to learn if you plan to work with data. Most data jobs require some level of SQL understanding. Jobs such as Data Analyst, Data Scientist, Data Engineer and Database Administrator.

I will be posting more content on SQL. Follow if you want to learn more on the topic.
