A Physical Data Flow Diagram is a diagram showing howparticular functions are performed within the data flow as opposed to a Logical DFD which only shows what functions are performed.
A flow proof is a proof that uses arrows to show the flow of a logical argument.

A physical data flow diagram shows how a system will be implemented, including the hardware, software, files, and people involved in the system whereas a logical data flow diagram focuses on the business and how the business operates.
For a physical Data Flow Diagram you explore into the logical DFD. for example, if you have a data flow arrow declared as "customer information" now the physical DFD would include in that data flow arrow "customer information = customer_name + customer_address". something along these lines Physical DFD shows how various functions are performed and who does them but Logical DFD strips away all physical constraints but does not restrict physical happenings from taking place.
difference between physical and logical data flow diagrams.
A branch simply means a diversion from linear program flow. An unconditional branch allows the programmer to move to specific parts of their code when the situation calls for it (jump, goto, function call, loop, etc.). Conditional branches allow the programmer to devise logical diversions in program flow based on certain criteria (if, switch, loop, etc.).
ER diagram is Entity Relationship Diagram which shows relationship between different entities in a process.... Data Flow diagram is a symbolic structure which shows the flow of data how it is used in diff stages in a particular process....

A simple circular flow model shows the flow of goods and services through the economy. It is basically a model that shows supply and demand in an economy.
