First Level Data flow Diagram(1st Level DFD) of Examination Management System :

First Level DFD (1st Level) of Examination 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 Examination Management System system as a whole. It also identifies internal data stores of Subject, Course, Branch, Student, Class that must be present in order for the Examination system to do its job, and shows the flow of data between the various parts of Timetable, Class, Course, Subject, Branch of the system.

Second Level Data flow Diagram(2nd Level DFD) of Examination Management System :

DFD Level 2 then goes one step deeper into parts of Level 1 of Examination. It may require more functionalities of Examination to reach the necessary level of detail about the Examination functioning. First Level DFD (1st Level) of Examination Management System shows how the system is divided into sub-systems (processes).
