Operational data store

An operational data store (or "ODS") is used for operational reporting and as a source of data for the enterprise data warehouse. It is a complementary element to an EDW in a , and is used for operational reporting, controls and decision making, as opposed to the EDW, which is used for tactical and strategic decision support. An ODS is not an intrinsic part of an EDH solution, although an EDH may be used to subsume some of the processing performed by an ODS and the EDW. An EDH is a broker of data. An ODS is certainly not.
