What is ETL?In computing, extract, transform, and load (ETL) refers to a process in database usage and especially in data warehousing that:

● Extracts data from outside sources● Transforms it to fit operational needs, which can

include quality levels● Loads it into the end target (database, more

specifically, operational data store, data mart, or data warehouse)

Data Sources C

ETL Scenario ● When there are many source systems to be

integrated

● When source systems are in different formats

● When this process needs to be run repeatedly

(e.g. daily, hourly, real time)

● To take advantage of pre-built

warehouses/marts. Many of these exist for

popular platforms such as PeopleSoft, SAP, JD

Edwards.
