Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Optimized for complex analytical queries
Why it's wrong here
OLAP systems are optimized for analytics, not OLTP.
- ✗
Stores historical data for trend analysis
Why it's wrong here
Historical data storage is typical of data warehouses (OLAP).
- ✓
Designed for high transaction throughput
Why this is correct
OLTP handles many concurrent transactions.
- ✓
Supports ACID transactions
Why this is correct
ACID is a key property of OLTP systems.
