Quizplus · Accepted Answer

A database extracted from the operational database for BI purposes typically contains just part of the operational database. This is because the entire operational database may not be necessary for the analytical purposes served by the BI database. Only the relevant data is extracted and consolidated into the BI database, which is optimized for reporting, analysis, and decision-making.
