Meet the SQL

SQL is a Structured Query Language created for accessing and manipulating data stored in databases. There are different versions of SQL and databases management systems that use SQL such as Microsoft SQL Server, PostgreSQL, MySQL, Oracle, etc.

There may be some specific knowledge needed for each DBMS, but at all, they use SQL with similar syntax. Using SQL, you can:

Create, change, delete and manipulate the tables
Create, change, delete and manipulate the data
Access and retrieve the data (records)
Create stored procedures in the database
Set permissions for procedures and tables

There is even an extension of SQL that lets you use it as a standard programming language: create variables, loops, if-else statements, and so on.

So let's submit the very first SQL query which shows all the data in the table songs.
