A- design the physical DFD level 1 for the following system. “In a video rental store the secretary receives a request from the customer to rent a movie then she saves the rent information in the rental file and gives the customer the bill. When the customer returns the video the secretary puts it in the video library file and signs the bill before returning it to the customer and finally return the rental information to the rental file. The manager wants a final report of all videos that have been rented so the secretary generates that report from the information in the rental file”.
