問題文
An agricultural cooperative wants members to see the current status of their grain deliveries at the moment they ask, not the next morning. The status lives in a separate scale-house system. What does this user need imply for the integration?
選択肢
- The integration should be designed at the data layer so that reports and analytics can be built on a single consolidated set of records.
- The request must be answered while the member waits, so the exchange has to be a call that asks the other system and returns a reply rather than a nightly transfer.
- The scale-house system should be replaced so that only one system holds status.
- The two systems should be kept loosely coupled by copying the whole delivery history into the customer platform on a schedule.
