How to Find the Right Datasets

Most people search “SQL dataset” and get overused, small samples. Instead, try:

✅ “raw data” – Unstructured, real-world data.
✅ “large dataset” – 100MB+, ideal for indexing and performance tuning.
✅ “financial transactions” – Good for fraud detection projects.
✅ “customer behavior” – Perfect for segmentation analysis.
✅ “time-series” – Best for forecasting trends.

Use filters to find datasets with over 1M rows for real SQL challenges.

Best Kaggle Datasets for SQL Projects

💰 PaySim Fraud Transactions – Detect financial fraud.
🚖 NYC Taxi Trip Data – 1.2B rows, great for query optimization.
📦 Walmart Sales Forecasting – Time-series analysis for sales trends.
🎵 Spotify Music Data – Find hidden patterns in music trends.
