mysql-tutorial is a practical, example-driven guide to MySQL that walks readers from installation and basics to everyday administration and performance techniques. It introduces schema design, data types, and constraints before moving to CRUD operations, joins, subqueries, and aggregation. Transaction control, indexes, and execution plans are explained with real queries so readers can see how design choices affect speed and integrity. The repository also touches on user management, permissions, backups, and common operational tasks that arise in production. Throughout, the emphasis is on clear SQL examples and short explanations that can be tested immediately in a local instance. It serves both as a learning track for newcomers and as a handy reference for developers who need to refresh core MySQL skills.
