The Importance of an Isomorphism in Domain Modeling

Eric Normand: Isomorphism is a set of mathematical objects that are in a certain relationship to each other. In the ideal case, we do have a one to one mapping with no leftover states. But that's not always possible and so we can't use the mathematics of isomorphism. He says software is not as precise as math but it gives us an advantage by allowing for perfect mappings.
