This Physical data flow diagram depicts how the system will be implemented, including the hardware, software, files, and users. It is designed so that the processes described in the logical data flow diagrams are correctly implemented to achieve the business's goal. The physical data flow diagram illustrates how the system executes the data flow. Due to the multiple data stores present in a system, physical data flow diagrams are typically more dynamic than logical data flow diagrams. The processes reflect the applications, software components, and manual protocols. A physical data flow diagram can be created using a logical data flow diagram.
