DFD for University Admission System

Data Flow Diagram (DFD) depicts the flow of information and the transformation applied when data moves in and out of a system. The overall system is represented and described using input, processing, and output in the DFD. More specifically, the data flow diagrams are responsible for carrying out two crucial tasks:

• It indicated data transformation as they move through the system.
• It shows the functions of data transformation.

The DFD also provided the information used during the information domain analysis. It serves as a basis for function modeling. From the context of a university admission system, the data flow diagram represents the flow of information in the entire student admission system. In this case, the input can be considered as an application form.
