How would you handle a practical scenario involving Transactions in SQL Server?

For a practical scenario involving Transactions, I would first clarify the business goal, scale, constraints, and the failure or quality attribute being tested. Transactions group related database operations into a unit that either commits together or rolls back together. The scenario centers on for an order creation process that writes order, items, and payment status, explain what belongs in one transaction and what should be handled asynchronously. I would then compare the main alternatives and tradeoffs, identify likely failure modes, and explain how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
