Data sources can include indexed files, external data, sequential files, archives, business applications, relational databases, etc. DataStage enables market research by offering quality data to help gain business intelligence.


Datastage ETL has a useful graphical front-end for developing tasks that handle the transformation, validation, processing, and loading of data from multiple sources, such as business applications such as Passport SAP, Oracle, mainframes for data storage systems.
