MySQL is a relational database management system that is built on SQL (Structured Query Language).
It allows you to save, retrieve, edit, and manage databases, which are collections of structured data stored on your server.
MySQL is part of the LAMP (Linux, Apache, MySQL, PHP), WAMP (Windows), and MAMP (MacOS) stacks. These are application stacks that serve as a foundation for website development.
Nowadays, MySQL is used by the majority of websites including blogs, and high-traffic websites like Facebook, YouTube, PayPal, Twitter, and LinkedIn.
MySQL uses a client-server model along with relational databases.
The client-server model works by storing the database on your server from which it can be accessed when a client requests it. In this context, a client is a program that is able to create SQL queries, such as MySQL itself, a browser, PHPMyAdmin, and so on.
Meanwhile, the relational database refers to stored data that is organized into different tables that are related to one another.
For instance, MySQL can hold addresses and name entries in separate tables, and present them together if requested.
For example, let’s say you want to open an online video. Your browser, through a website, requests data from the database that holds the video by sending SQL commands to the server.
Then, MySQL compiles necessary information about that file – such as published date, uploader info, and comments – that are spread on different tables.
After that, MySQL sends the data back to the browser so it can display the video as a whole.
SQL is a standard language used to access relational databases. It contains commands that allow you to define database objects, update data, and control user permissions.
On the other hand, MySQL is one of the Relational Database Management Systems that use SQL’s predefined commands to establish server-client communication.
While they are two different items, they work together to achieve the same goal – making your database management easier.
There are many reasons why MySQL is very popular among developers, such as:
