IPA IP 2024 Question 13
A question IPA Japan published in 令和6年度 ITパスポート試験 公開問題 問13, translated into English. ITPEC is based on the same exams.
At financial institutions, for individuals and corporations that are the same customer and hold multiple accounts, work is performed to aggregate the accounts by using clues such as the name or corporate name, the date of birth or date of establishment, the telephone number, and the address or location, and to grasp accurately the total amount of deposits for each customer. Which of the following is the most appropriate term that represents the procedure of putting together the multiple accounts held by a customer in this way for each customer and managing them centrally?
Explanation
Name-based aggregation — gathering every account a customer holds under that one customer, matched by name, date of birth, telephone number and address.
Records of one customer are often scattered: accounts opened at different branches or times, with a name spelled differently or an old address. Name-based aggregation matches them on several identifying items and links them to one customer, so the institution can manage the customer centrally and know, for example, the total of that customer’s deposits. Japanese banks must keep this data ready, because deposit insurance protects a set amount per depositor per bank, not per account.
Answer (d)
Why not others:
- •(a) — account aggregation is a service that collects a user’s account information from several banks, securities firms and card companies and shows it in one place (a household-budget app, for example); it serves the user across institutions, not one institution organizing its own customers
- •(b) — key mapping assigns functions to keys or matches key values between systems; it is not the term for consolidating a customer’s accounts
- •(c) — vertical integration is a company taking over stages upstream or downstream in its own supply chain, such as a manufacturer buying a retailer
Key rule: Consolidating one customer’s scattered records into one by matching identifying items is name-based aggregation; showing a user’s accounts at many institutions together is account aggregation.
