Logical vs physical data model before discussing the difference between logical and physical data model, we must know what a data model is a data model is a representation that describes the data and the relationships among them for a certain process. The difference between physical and logical topology is present and can be demonstrated in a shared ethernet network that employs hubs instead of switches with this type of connection, the logical topology looks as if each node is connected into the same bus.
