    - There are two types of DFD

    Logical DFD
    - This DFD concentrates on the system process, and flow of data in the system.

    - For example in a Banking software system, how data is moved between different entities.

    Physical DFD
    - This DFD shows how the data flow is actually implemented in the system.

    - It is more specific and close to the implementation.
