ETL Datawarehouses

ETL (Extract, Transform, Load) is a key process in data warehousing, enabling the integration of data from multiple sources into a centralized database. The process begins by extracting data from original sources, followed by transforming it to ensure quality, deduplication, and combination, and finally loading it into the target database. ETL tools streamline this process, allowing companies to consolidate diverse data types and ensure seamless integration for effective data analysis and decision-making.
