Levelling of DFD
As we know that it is easier to solve a problem in top down manner that is starting with an overview and then working out the details. Similarly, it is easier to understand levelled DFD as compared to single large detailed DFD.
Levelled DFD are drawn in top down approach, i.e. at top level o level DFD or context in made then this o level DFD is expanded to level 1 DFD from (expanding and dividing ) the main process bubble of o level DFD.
At level 1 the bubbles are also called as the sub processes. To draw level 2DFD, these sub processes are further expanded & divided individually in 3to 5 bubbles and so on. A detailed illustration of levelling is shown in fig 4.17.
