+We are allowing to place only a single product within an order. In a real-world application, the `Order` entity would be much more complex. However, the complexity of the `Order` entity doesn't effect modularity, so we keep it simple to focus on modularity in this tutorial. We are inheriting from the [`CreationAuditedAggregateRoot` class](../../framework/architecture/domain-driven-design/entities.md) since I want to know when an order has been created and who has created it.
