問題文
When a new customer is created in the CRM, a distributor needs that same customer record to appear in the billing system, the shipping system, and the support system, kept up to date going forward. Which use case fits best?
選択肢
- A correlation, which would only update the records that already exist in every one of the systems being connected.
- A broadcast, which continuously feeds each new CRM customer out to the billing, shipping, and support systems as it is created or changed.
- A one-time migration; moving the record to three systems is by definition a single cutover event that never needs to be repeated afterward.
- An aggregation, which would instead collect data from the three target systems and merge it into a single response for the CRM to display on demand.
