Operational data store (ODS)

Operational data store

A subject-oriented system that is optimized for looking up one or two records at a time for decision making. An operational data store is a hybrid form of data warehouse that contains timely, current, integrated information. The data typically is of a higher level granularity than the transaction. You can use an operational data store for clerical, day-to-day decision making. This data can serve as the common source of data for data warehouses.
