Explain in detail about Functional Modelling.

This model explains the computations that take place within a system.
This model is useful when the transformation from the inputs to outputs is difficult.
The functional model of a system can be shown by a data Flow Diagram (DFD).

Data Flow Diagrams/Data Flow Graph/Bubble chart

A DFD is a graphical shown that depicts the information flow and the transforms that are applied as the data move from input to output.
Level 0 DFD also known as fundamental system model or context model shows the whole software as a single bubble with input and output data indicated by incoming and outgoing arrow
