No, you're not doing either. When you build a logical data model, you define entities by giving them names and properties, and you define the relationships between those entities. As far as your logical data model is concerned, you don't have a set of entities within a collection, just the one representational entity. It's only when you get to your physical data model that entities become tables, and properties become fields, and relationships become DRI.
