عرض عملي: اختيار أسلوب لكل واجهة في Larkspur

خطوة بخطوة

1. List interfaces from the context diagram: ERP, CRM, payment gateway, carriers, stores, marketing platform.
2. For each, write the latency need, volume, and what happens if it is down.
3. Choose: payment authorization as a synchronous API; order and stock changes as events; finance posting as nightly batch; carrier labels as API with a file fallback; marketing audiences as a daily file.
4. Planned mistake: choose real-time events for the marketing export "to be modern". Fix: show that the campaign tool refreshes once a day, so a daily file costs less and is easier to reconcile.
5. Add owner, frequency, volume, and SLA columns; flag interfaces with no owner.
6. Present three decisions and their trade-offs to a role-played integration lead.
