問題文
A team debates whether a piece of logic that combines two System APIs and applies business rules belongs in a System API or a Process API. Which guidance is correct?
選択肢
- It must be duplicated into every Experience API, so that each channel keeps its own copy of the same rules.
- It belongs in the System API, given that embedding business rules directly into the layer that unlocks a system of record keeps it reusable.
- It belongs in a Process API, because orchestrating multiple systems and applying business rules is the Process layer's responsibility, keeping System APIs reusable.
- It belongs in neither layer; combining two systems and applying rules can only ever be done inside the mobile app itself.
