Updated: Feb 19, 2022

For an absolute beginner, SQL stands for structured Query Language. It is the standard language for relational database management systems and is used for operations like creating, deleting, updating and retrieving data from the database. The data in RDBMS is stored in tables and tables are related to each other with common/unique keys. SQL queries operate on one or more tables at a time to manipulate data in one or more tables in a go.

Talking a bit more about SQL, you can use SQL queries with all RDBMS systems including Oracle, mySQL, SQL Server, Sybase, Informix, Postgres and the list is very long. A key point to note here is that many SQL systems like MYSQL have custom SQL extensions as well, custom extensions provide additional features on top of the standard SQL.

Though mastering the standard SQL covers almost everything you need to do with a database, but knowledge of database specific extensions can greatly enhance your productivity.
