OLTP systems are primarily used for which of the following?

• A. Historical Analytics
• B. Transactional Processing With Many Reads And Writes
• C. Large-Scale Batch Processing
• D. Graph Traversal

Answer: (B)

OLTP systems are built for handling many quick, concurrent transactions with fast response times and strict data integrity. They focus on processing numerous reads and writes in real time, using ACID properties to keep each operation reliable and consistent. This makes them ideal for everyday business applications like order entry, payments, and inventory updates where immediate, accurate updates are essential. The other options describe workloads more aligned with OLAP or batch processing—historical analytics involve complex queries over large datasets, large-scale batch processing handles big offline jobs, and graph traversal is typically associated with graph databases and analytics rather than real-time transactional processing.
