Data Flow Diagram

A data flow diagram refers to the representation of the flow of data and functions in a program or in a part of it.
The data flow diagram is especially useful when handling a large code and the programmer needs to find or isolate bugs from the code.
Its is also useful for the end user where he can identify the flow of operations in a system. He may assume an operation like button click and he could then find the ways to acheive a successful completion of his work, through the data flow diagram.
Generally it explains the different ways in which an input leads the system to produce a specific output.
