ITPEC FE Morning October 2020 Question 64
ITPEC FE Morning October 2020 — Question 64 of 80
Big Data Utilization Classification — classify big data use cases by feedback destination (all vs. individual) and reflection timing (periodic vs. immediate).
The table has two axes:
- Feedback destination: all customers vs. individual customer
- Reflection timing: once every fixed period vs. immediately
Cell D = individual customer + immediately.
- •(a) Location data from a registered member's smartphone → personalized product recommendations displayed instantly on their phone. Individual + Immediate = D ✓
- •(b) Purchase data from member cards → coupons issued for the next month based on last month's volume. Individual + Fixed period = C
- •(c) Traffic status published on a website by analyzing car movement data in real time. All customers + Immediate = B
- •(d) Monthly best-selling product rankings from POS data displayed on in-store monitors. All customers + Fixed period = A
Key rule: match each scenario on two axes — who receives the output (all vs. one person) and when it is reflected (scheduled vs. real-time).
