A physical data model elaborates on the logical data model by assigning each column with type, length, nullable, etc. Validate logical model against user requirements. It describes the inputs (sources), outputs (destinations), databases (data stores), procedures (data flows) all in a format that meets the user requirements. In contrast, a physical design is like a set of blueprints for the actual construction of a building. The physical Data Model describes the database-specific implementation of the data model. Difference between Logical & Physical Design of a Network When we look at the differences between logical design and physical design of a network it is easy to think of it as the logical as the functional part and physical as the seeing it part. •An IoT system comprises a number of functional blocks that provide the system the capabilities for identification, At its basic level, the topology of a network refers to the way in which all its pieces have been connected.
