Establishing clear interfaces
Now, we can start to decouple SalesOrderService and WarehouseService. To do so, we need to apply the concepts reviewed in Chapter 5, Introducing Refactoring Principles and in the previous section, such as defining clear interfaces for the services so that we can encapsulate all their work to the outside world.
