What does MySQL mean?

MySQL is a combination of two words: My and SQL.

"My" was the initials of Michael Widenius's daughter. He is the co-founder of the MySQL. SQL means Structured Query language.

MySQL databases are relational.

Relational means, MySQL stores data in separate tables, instead of at one place in the storeroom. It follows a structure, consist of rows, columns, and tables.

This logical structure provides a flexible programming environment.

MySQL is open-source.

Being open-source means that anyone can download the software from the site. They can modify or use it anyway they see fit.

Though you have to use this software under the GPL (GNU General public License). 

There is also a license-free version you can buy from the Oracle if you want to use it for commercial purpose.

It is easy to use and works in the background. MySQL can be scalable to process large data, with the help of powerful processing system and RAM.
