4. SQL
SQL lets you query and shape relational data. Testers use it to validate integrity, spot anomalies, and confirm business logic at the source.
Why It's Important
Bad data sinks good features. SQL catches mismatches early and proves correctness beyond the UI.
How to Improve SQL Skills
Master the core: SELECT, JOINs, GROUP BY, HAVING, subqueries. Get fast at reading execution plans.
Work with real datasets: Use sample schemas (e.g., Sakila, Northwind) and production-like snapshots where allowed.
Study indexing: B-tree basics, covering indexes, selective columns, and when not to index.
Learn transactions: ACID, isolation levels, deadlocks. Test under contention.
Write for performance: Avoid N+1 patterns, prefer set-based ops, paginate properly.
Understand design: Normalization, keys, relationships, constraints. Cleaner schemas, cleaner tests.
