MySQL in WordPress
SQL is Structured Query Language and an open source software. It is used to create and manage databases and hook them up with any type of front-end software (hint: WordPress) to combine and show data to users. The process is called running an SQL query.
WordPress uses MySQL database to store all of its information. Upon user request, it stores and fetches data from the database and show it to the user.
In order to understand and use WordPress to its full potential, you need to understand what is database and how do it work at least at a basic level. It will help you to solve itty bitty problems yourself instead of hiring a WordPress database expert.

Additional to these tables, plugins in WordPress (see article) can also create their own dedicated tables to store data however most plugins don’t create tables in database.
