Zero Level Data flow Diagram(0 Level DFD) of Result Management System :
This is the Zero Level DFD of Result Management System, where we have eloborated the high level process of Result Management. It’s a basic overview of the whole Result Management System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Result,Teacher and Semester showing the system as a single high-level process, with its relationship to external entities of Student,Exam and Class.

First Level Data flow Diagram(1st Level DFD) of Result Management System :
First Level DFD (1st Level) of Result Management System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Result Management System system as a whole. It also identifies internal data stores of Semester, Teacher, Result, Subject, Class that must be present in order for the Result Management system to do its job, and shows the flow of data between the various parts of Student, Class, Teacher, Semester, Result of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Result Management.Main entities and output of First Level DFD (1st Level DFD):
