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, typically a data warehouse. The ETL process consists of three main steps: extraction, where data is collected from diverse sources such as databases, files, or APIs; transformation, which involves cleaning, enriching, and structuring the data to meet business needs; and loading, where the processed data is stored in a target system for analysis and reporting. ETL plays a vital role in ensuring data integrity and accessibility for effective decision-making in organizations.
