What is ETL?

ETL is a type of data integration that refers to the three steps (Extract, Transform and Load) used to blend data from multiple sources. It’s often used to build a Data warehouse. During this process, data is taken (extracted) from a source system, converted (transformed) into a format that can be analyzed, and stored (loaded) into a data warehouse or other system.

  • Extract: – This is the process of reading data from a database. In this stage, the data is collected, often from multiple and different types of sources. The data can be in various formats like relational databases, No SQL, XML or Flat files
  • Transformation: – This is the process of converting the extracted data from its previous form into the form it needs to be in so that it can be placed into another database. Transformation occurs by using rules or lookup tables or by combining the data with other data.
  • Load: – The third and final step of the ETL process is loading. In this step, the transformed data is finally loaded into the data warehouse.

Sometimes the data is updated by loading into the data warehouse very frequently and sometimes it is done after longer but regular intervals.

The target may be Data warehouse or data mart.
