Question

Develop a physical DFD that models the process of grocery shopping, from the time you write down a shopping list until the time you store purchased groceries in your home. Construct your DFD as a linear sequence of processes. Now develop a logical DFD to describe the same scenario. Try to develop a diagram that is equally valid as a logical description of the way you currently buy groceries and as a logical description of ways you might buy groceries without ever leaving your home.
