Practical No 8
Develop a data dlow diagram using dfd ,division table & ER diagram Data Flow Diagrams are used to represent the flow of data as well as the processes and functions involved to store, manipulate, and distribute data among various components of the system and between the system and the environment of the system by a specific set of graphical representations. It also depicts the logical flow of information in a system and appropriately defines and determines the physical requirements for the construction of the system. The key features of a Data Flow Diagram involve simplicity of notation as well as generation of a clear overview of the manual and automated requirements of the system. Level 0 DFD : This level is also known as Context Level DFD. At this level, only the interacting inputs and outputs with a system are described. The DFD of this level is shown in the diagram Level 1 DFD : At this level, more detailed information is given about the processing of the ATM system....
