Data extraction is the process of retrieving data from one or more sources. Often, data extractions are performed to restructure poorly organized systems or to rearrange data for analytical purposes. Data extraction is usually associated with data transformation and data loading to form ETL processing.
During data extractions, information is parsed and taken from disparate sources to be arranged in a data warehouse. For organizations with large data volumes, data extraction can consume a great deal of time and resources while other mission-critical applications are significantly slowed. Moreover, data extraction is only the first step in arranging and manipulating records in data warehouses. Along with data transformation and data loading, data extraction can take several days to complete, placing a major burden on an organization's resources.
