Within the framework of VES modeling, it is imperative to discern the disparities between a smooth model and a layered model?

Draw an entity relationship diagram (ERD) for the following situations: 2. Whenever new patients are seen for the first time, they complete a patient information form that asks their name, address, phone number, and insurance carrier, all of which are stored in the patient information file.
