1. SQL

SQL is the backbone of relational data. Queries, joins, indexes, transactions—this is where production support lives when the app slows or data goes sideways. You read execution plans, trim fat from queries, and keep data clean and available.

Why It's Important

When production flares up, SQL gives you clarity. It lets you find bad queries, fix blocking, validate data, and keep service levels intact without guesswork.

How to Improve SQL Skills

1. Nail the fundamentals: SELECT, JOIN, GROUP BY, subqueries. Aim for precision and predictable results.
2. Think in indexes: Understand clustered vs. nonclustered, covering indexes, and when an index hurts more than it helps.
3. Read query plans: Learn to spot scans vs. seeks, key lookups, cardinality issues, and sort/hash hotspots.
4. Master transactions: Isolation levels, locks, deadlocks, retry logic. Protect integrity without freezing throughput.
5. Use advanced features wisely: Stored procedures, triggers, window functions, CTEs—cleanly and with measurement.
6. Watch performance: Monitor slow queries, connection pools, and resource pressure. Build a habit of baselining.
7. Hone migration chops: Write safe schema changes, backfill data incrementally, plan rollback paths.
8. Practice relentlessly: Recreate real incidents. Fix them faster. Document what you learn.
