Scott changes the description. Adams changes the price. If Adams saves his change before Scott does, Scott’s change has disappeared.In your problem definition you mention inserting an order. If order updates are allowed, the lost update can occur. I see in part 2 order lines are only inserted, there is no update and lost updates will not occur.
