The correct answer: all of the above

ETL is an acronym for three database functions extract, transform, load that is combined into one tool to extract the data from a database and load it into another database.

  • Extract is the process of reading data from internal and external databases
  • Transform is the process of converting the extracted data into the form required form.
  • Load is the process of loads information into the target database.
