What is MySQL?

MySQL is a relational database management system based on SQL–Structured Query Language. It is available in both open-source and commercial versions and is compatible with various platforms using all major languages and middleware.

MySQL is the most widely used database, according to the developer survey from ScaleGrid.  MySQL is broadly utilized as a part of the LAMP (Linux, Apache, MySQL, PHP) stack of open-source programs that form many websites on the Internet, including Facebook, Twitter, and YouTube.

Advantages of MySQL

Here are some of the main advantages of MySQL:

  • Data Security: MySQL is globally renowned for being the most secure and reliable database management system used in popular web applications, including WordPress, Drupal, Joomla, Facebook, and Twitter.
  • High Performance: MySQL features a different storage-engine framework that facilitates system administrators to configure the MySQL database server for flawless performance.
  • Cost-Effective: The database is open-source and free.

Disadvantages Of MySQL

Here are some of the key disadvantages of MySQL:

  • MySQL does not support a huge database size efficiently.
  • It is challenging to debug stored procedures.
