SQL Basics

SQL stands for Structured Query Language. It is a system for querying — requesting, filtering, and outputting — data from relational databases.

Developed in the 1970s, SQL was originally called SEQUEL. For this reason, today it is sometimes pronounced “Sequel” and sometimes pronounced “S.Q.L.” Either pronunciation is acceptable

Although there are many “flavors” of SQL, SQL in some form can be used for querying data from most relational database systems, including MySQL, SQLite, Oracle, Microsoft SQL Server, PostgreSQL, IBM DB2, Microsoft Azure SQL Database, Apache Hive, etc. databases.
