An order-entry system processes thousands of small insert/update transactions per second with millisecond response requirements. Which workload type?
A.OLAP — analytical processing
OLAP runs analytical queries over large historical datasets.
B.OLTP — transactional processing
High-volume small transactions = OLTP. Correct.
C.Batch processing
Batch describes scheduling, not the transaction pattern.
D.Data warehousing
Warehousing is analytical storage — not transaction processing.
Why this answer
OLTP = many small read/write transactions, low latency, current data — the classic order-entry/banking workload. OLAP/warehousing = large scans and aggregations over historical data for analysis.
