The advantages of DFD?
When it comes to conveying how information data flows through systems (and how that data is transformed in the process), data flow diagrams (DFDs) are the method of choice over technical descriptions for three principal reasons.1. DFDs are easier to understand by technical and nontechnical audiences2. DFDs can provide a high level system overview, complete with boundaries and connections to other systems3. DFDs can provide a detailed representation of system components.DFDs help system designers and others during initial analysis stages visualize a current system or one that may be necessary to meet new requirements. Systems analysts prefer working with DFDs, particularly when they require a clear understanding of the boundary between existing systems and postulated systems.As we have seen, the DFD method is an element of object-oriented analysis and is widely used. Use of DFDs promotes quick and relatively easy project code development. DFDs are easy to learn with their few-and simple-to-understand symbols (once you decide on a particular DFD model). The syntax used for designing DFDs is simple, employing English nouns or noun-adjective-verb constructs.http://www.stc.org/confproceed/2000/PDFs/00098.pdf

Brief in What is the Difference between physical DFD and logical DFD?
A logical DFD makes it easier to communicate for the employees of an organization, leads to more stable systems, allows for better understanding of the system by analysts, is flexible and easy to maintain, and allows the user to remove redundancies easily. On the other hand, a physical DFD is clear on division between manual and automated processes, gives detailed description of processes, identifies temporary data stores, and adds more controls to make the system more efficient and simple. simply put… 1. Logical DFDs are not concerned about how the system is or will be constructed while Physical DFDs show how the system is or will be constructed. 2. Physical DFDs are more realistic and complex while Logical DFDs are simpler but provide an easier understanding view
