Extract, Transform, Load Process

The Extract, Transform, Load (ETL) process is a way to gather data from different sources, prepare it for analysis, and then store it in a centralized system. Extraction involves collecting raw data from various databases or files. Transformation cleans and organizes this data—such as removing errors, formatting, or combining information. Loading then moves the cleaned data into a data warehouse or storage system for easier access and analysis. ETL helps businesses make better decisions by ensuring their data is accurate, consistent, and ready for reporting.
