Question

Quizplus · Accepted Answer

The data warehouse typically contains historical data, including transaction histories, whereas the operational database is focused on current transactions. Therefore, the data warehouse within an ERP program is likely to contain five to ten years of transaction histories. Option A is incorrect because the operational database is not typically used for long-term storage of historical data. Option B is incorrect because the data warehouse is typically not updated in real-time or even daily, as it is intended to support historical analysis rather than immediate operational decision-making. Option D may be true, but it is not necessarily a defining characteristic of the data warehouse within an ERP program.
