Three well-known data models of this type are relational data models, network data models and hierarchical data models. The relational model represents data as relations, or tables.
What is logical and physical representation of data with example?
A logical data model is a model that describes data as much as possible, without regard to how they will be physically implemented in the database. In contrast, a physical data model is a model that represents how the actual database is built. Hence, this is the main difference between logical and physical data model.
