ETL (Extract Transform Load)

ETL — Extract, Transform, Load — is a data pipeline process used to move data from source systems into a target destination such as a CRM or data warehouse. The Extract phase pulls raw data from one or more sources (a legacy CRM, a spreadsheet, or an external database). The Transform phase converts, cleans, and restructures the data to match the target system's format, data types, and business rules. The Load phase uploads the processed data into the target system in the correct sequence. ETL is the technical foundation of CRM data migrations, ongoing data synchronization pipelines, and data warehouse population. The reliability and scalability of ETL processes directly affect the quality and timeliness of data available in enterprise CRM systems.
