A Correct answer
Explanation

An Operational Data Store (ODS) is subject-oriented (organized by business subjects), integrated (consistent data), current-valued (contains real-time or near-real-time data), and volatile (data is updated frequently). Unlike data warehouses, ODS systems support operational decision-making with current rather than historical data.
