ETL & ELT Explained in 4 minutes
Learn the fundamentals of ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform). We'll see why ETL and ELT processes are crucial for data integration & consolidation, allowing better decision-making and business intelligence.
ETL, or Extract, Transform, Load, consolidates data from various sources. It extracts data, transforms it for consistency, then loads it into a central destination like a data warehouse.
ELT, Extract/Load/Transform, directly loads data without initial transformation, ideal for real-time integration, especially in cloud environments. ELT often accompanies data lakes, offering flexibility in data storage and transformation on demand.
