📝 SQL Views Notes : Simple vs Materialized + Dependency Management Simple View: virtual | always fresh | but slow for heavy queries. Materialized View: precomputed | fast | but needs scheduled refresh 🔹 Dependency Rule: Base Table → Parent View → Child View Always refresh parent first → child next ✅ Keeps your dashboards & pipelines reliable. 💡For complex pipelines, automate refreshes with orchestration tools like Airflow DAG. Always log refreshes to track timing and errors. 💡 Materialized views aren’t just “precomputed tables” — proper refresh order and dependency management are key to reliable, high-performance analytics pipelines. #DataEngineering #SQL #MaterializedViews #Analytics #ETL #DataOps
