The Venn Diagram

If there's a pizza that you want people to be able to order, you better be able to write it down. And things that you can encode that don't really mean anything and just throw an error. It's better to be on that side if you have to make the choice. The conceptual model, the mapping to the domain model might be really awkward. Right, there might be, it just might be like really hairy code. We often do for expediency or we're inheriting an existing model and we can only modify it in small ways. We can't replace it. They don't mean anything will never translate them to anything.
