It is based on Structured Query Language (SQL) and is one of the most widely used database systems in the world. MySQL is particularly popular in web development environments and is a core component of the LAMP stack (Linux, Apache, MySQL, PHP/Python/Perl).

Key Features:

  • Open Source and Free: Available under the GNU General Public License (GPL).
  • High Performance: Optimized for speed and efficiency in high-load environments.
  • Scalability: Supports large databases and high transaction volumes.
  • Multi-User Access: Concurrent access with high reliability and security.
  • Replication Support: Master-slave and master-master replication for distributed systems.
  • Storage Engines: Supports various storage engines like InnoDB (default), MyISAM, MEMORY, etc.

Architecture:

  • Client-Server Model: MySQL operates on a client-server architecture.
  • Storage Engine Layer: Abstracts how data is stored and retrieved.
