What is ETL?

ETL stands for Extract, Transform, and Load. It is a process of gathering data from various sources, transforming and converting it into a consistent format, and then loading it into a data warehouse or database. Extraction involves accessing and retrieving data from different systems, such as databases, files, or APIs. Transformation entails cleaning, filtering, and structuring the extracted data to fit the desired format or standards. Finally, loading refers to the process of inserting the transformed data into a centralized repository for analysis and reporting. ETL is crucial for organizations to integrate disparate data sources and obtain meaningful insights for decision-making.
