MySQL Learning Resources [2026]

MySQL has been in production longer than most web developers have been alive. Released in 1995, it became the M in the LAMP stack that powered the first generation of web applications — WordPress, Drupal, Magento, and countless custom applications still running in production today. Facebook ran MySQL at scale so extreme they had to write custom replication infrastructure. Twitter used it. Booking.com's entire platform is MySQL. The database's ubiquity is self-reinforcing: it's what PHP tutorials teach, what shared hosting runs, what most junior developers encounter first. MySQL 8.0 narrowed the feature gap with PostgreSQL significantly — window functions, CTEs, JSON columns, and better index types. For developers targeting web backend, PHP, or data analyst roles, MySQL knowledge is a practical necessity.

• ✓MySQL appears in more job postings than any other relational database in web development contexts. PHP roles, WordPress agencies, and e-commerce backend positions routinely list MySQL as a requirement.
• ✓MySQL is the entry point for most SQL learners. The skills transfer directly to PostgreSQL with minimal friction — mastering MySQL means you can work on the two most common relational databases with no additional learning curve.
• ✓Database query performance optimisation — indexes, EXPLAIN plans, query analysis — is one of the most impactful skills a backend developer can develop. MySQL's tooling makes this learnable without a DBA background.
• ✓MySQL 8.0's addition of window functions, recursive CTEs, and role-based access control means modern MySQL skills are relevant for analytical and data engineering roles, not just basic CRUD applications.
