extract transform load

Extract, Transform, Load (ETL) is a crucial process in data engineering that facilitates the movement of data from various sources to a target system. The process consists of three main steps: extraction, where data is collected from databases, files, or APIs; transformation, which involves modifying and enriching the data to meet specific requirements; and loading, where the processed data is stored in a destination such as a database or data warehouse. ETL is essential for ensuring that data is accurate, consistent, and ready for analysis, making it a foundational component of data management and analytics workflows.
