There are several software tools that can be used to support the process, but sometimes specific software programs need to be coded to achieve the objective. In such case ETL (Extract, Transform and Load) is a process in data warehousing responsible for pulling data out of the source systems and placing it into a data warehouse. ETL is a set of computer programs or processes that capture the appropriate data from the routine or operational systems, clean it up, and store it a standard and consistent format.
