問題文
A retailer already has separate order, shipment and product APIs. Every time a new front end needs a different combination of those three, a developer builds another API that calls all three and returns a joined result. The architect wants to stop that pattern. Which role is Anypoint DataGraph suited to here?
選択肢
- Letting each front end query the fields it needs across the three existing APIs through one unified schema, so that a new combination does not require a new API to be built
- Caching the joined result of the three existing APIs, so that front ends read a prepared response instead of calling the three APIs each time
- Replacing the three existing APIs with one API that owns the joined model, so that front ends have a single implementation to call and maintain
- Letting each front end call the fields it needs across the three existing APIs through one shared proxy, so that a new combination does not require a new contract to be signed
