DA0-002 Data Concepts and Environments Practice Question
A hospital's patient records system must process thousands of small transactions per second. Which type of database system is best suited for this workload?
⚠ Common exam trap
It's easy for candidates to confuse OLTP with OLAP, mistakenly thinking that 'processing many transactions' implies analytical processing, when in fact OLTP is the correct choice for high-frequency, small, write-heavy workloads.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
OLTP
OLTP (Online Transaction Processing) systems are designed to handle a high volume of small, concurrent transactions with low latency and high concurrency. This makes them ideal for a hospital patient records system that must process thousands of small transactions per second, such as patient check-ins, prescription updates, and billing entries.
