Top Free SQL courses from Scratch for Beginners and Advanced
Hello everyone In this video I will review the top free SQL courses from scratch for beginners and advanced.
I have been working at IT for several years and in this video I will tell you about the top free courses that will help you learn SQL. I'll start, perhaps, with a definition. What is SQL? It is a Structured Query Language that allows storing, manipulating and retrieving data from relational databases. What SQL allows us to do: access data in relational database management systems, describe data (their structure), define and manage data in the database, interact with other languages through SQL modules, create and delete databases and tables, create views, stored procedures and functions in the database, set permissions to access tables, procedures and views.
