@zoout: Everyone wants to learn: Excel ✅ Power BI ✅ Tableau ✅ Python ✅ But without SQL… you are incomplete in Data Analytics. 📊 SQL is the backbone of real-world data jobs. If you can’t query data, clean data, join tables, and analyze databases… dashboards alone won’t save you. In these notes I covered: 1️⃣ SELECT, WHERE, ORDER BY 2️⃣ GROUP BY & HAVING 3️⃣ JOINS & Relationships 4️⃣ Subqueries 5️⃣ Aggregate Functions 6️⃣ Primary & Foreign Keys 7️⃣ Normalization 8️⃣ Window Functions 9️⃣ Database Concepts 🔟 Real SQL roadmap for Data Analysts Most beginners ignore SQL and waste months. Learn SQL first. Then tools become easier. #SQL #DataAnalytics #DataScience #PowerBI #Tableau
