問題文
A contact center agent is on a call. A separate collections process records the customer's payment against the case in Salesforce, and the agent must see it appear without reloading the page. A second request in the same project asks for the customer's historical invoices, which stay in the finance system. How should these two requests be classified?
選択肢
- The payment is a change to Salesforce data that the screen must follow, so it is a subscription on the page; the invoices are data outside Salesforce that must be read live, so they are the virtual pattern.
- Both are the virtual pattern, because in both cases the agent needs to see something that was not on the page when it was opened.
- Both are the data synchronization pattern.
- Both should be handled by having the page poll for changes every few seconds, because a single mechanism is easier to operate than two and the polling interval can be tuned separately for each list.
