Скачать или смотреть What is SQL ("sequel") & What It Does - PLUS How to Learn it for Free as a Beginner with No Experie

A data analyst uses SQL to select and manipulate data from databases.
Excel is not a database, it's just spreadsheet software, and often contains a subset of data that was selected using SQL on a much larger database.
SQL is the easiest programming language for beginners with no experience because there are only about 30 different functions to use.
But because it's technically a programming language, most people are intimidated to try to learn it, so the supply of people who can do it is much smaller than the demand.
That's part of why data analysts get paid so well!
