Your question is Delivery App Design and Schema. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Create a rough design for a delivery application and design an RDBMS schema for it.
Keep the scope to core entities, request flow, and data model. Explain how you would support order placement, rider assignment, status tracking, and cancellations, and note any assumptions you make about scale or consistency.
