You have completed the MySQL course. Here are natural next steps:
- PostgreSQL — MySQL's most capable open-source competitor. Adds native JSON (JSONB), better window functions, full-text search, and stricter SQL standards compliance.
- SQLite — The world's most deployed database. Zero configuration, a single file, and perfect for local tools, mobile apps, and testing.
- Database design — Study normalization (1NF, 2NF, 3NF, BCNF), ER diagrams, and indexing strategies. The schema design behind an application determines its performance for years.
- Query optimization — Learn how MySQL's query planner works. Use
EXPLAINto see execution plans, add indexes, and avoid full table scans. - Transactions — MySQL supports ACID transactions with
BEGIN,COMMIT, andROLLBACK. Understand isolation levels (READ COMMITTED, REPEATABLE READ, SERIALIZABLE). - Replication — MySQL's primary-replica replication scales reads horizontally across many servers.
