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 ETL process consists of three main steps: extraction, where data is collected from diverse sources such as 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 target system, such as a data warehouse. This systematic approach ensures that data is clean, organized, and ready for analysis, enabling businesses to make informed decisions based on accurate information.
