Respuesta :
The growth of the demand for instant, on-demand access to dispersed information is a more pressing need to close the gap between operational data and strategic objectives.
What is operational data?
- Operational reporting and the enterprise data warehouse both draw data from an operational data store (ODS) (EDW).
- Operational data is used for operational reporting, controls, and decision-making as opposed to the EDW, which is used for tactical and strategic decision support.
- Operational data is a supplementary component to an EDW in a decision support environment.
- A database called an ODS is made to combine data from various sources for further processing, reporting, control, and operational decision support.
- The information is not returned to operational systems, unlike a production master data store. It could be given to the data warehouse for reporting and for further processing.
