To me:
1) Entities/Business Objects/Business Model Objects – the actual objects (nouns) in the business domain. For example “Order” and “OrderItem”. “Order” could have a property of “OrderDate”, and function called “GetOrderItems”
2) Data Transfer Objects – serializable property bag representations of your Entities. Using the example above, the function “GetOrderItems” would be missing from your “Order” DTO.
