Extract, Transform and Load – ETL, forms the fundamental process behind any kind of data management.

ETL – Extraction, Transformation and Loading, is a trilogy of processes that collects varied source data from heterogeneous databases and transforms them into disparate data warehouses.

Extract:

  • Recovers necessary data with optimum usage of resources
  • Should not disturb data sources, performance and functioning

Transform:

  • Filtration, cleansing and preparation of data extracted, with lookup tables
  • Authentication of records, refutation and integration of data

Load:
