MySQL
Web で最も広く使われているオープンソースのデータベース。
MySQL is the open-source database behind WordPress, countless PHP and Laravel apps, and some of the largest sites on the web. You already speak SQL from the SQL track, so this course maps what you know onto MySQL 8.4 LTS and shows where it differs from PostgreSQL: the mysql client, data types, utf8mb4 for Persian text and emoji, InnoDB and its clustered primary key, EXPLAIN, transactions under REPEATABLE READ, upserts with ON DUPLICATE KEY UPDATE, least-privilege users and backups you can actually restore.
Every lesson is short and practical, and the result sets stay tiny, so you can check every answer by eye.
