The DFD is also known as Data Flow Graph or Bubble Chart. The DFD is used to represent increasing information flow and functional details. Also DFD can be stated as the starting point of the design phase that functionally decomposes the requirements specifications down to the lowest level of detail. A Level 0 also called a fundamental
