Computerized Examination System Dataflow Diagram

Posted By namita on June 30, 2017

Computerized Examination System Data flow diagram is often used as a preliminary step to create an overview of the Examination without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Examination process. It contains all of the userflow and their entities such all the flow of Exams, Papers, Students, Results, Teachers, Questions, Authentication. All of the below diagrams has been used for the visualization of data processing and structured design of the Examination process and working flow.


Zero Level Data flow Diagram(0 Level DFD) of Computerized Examination System :

This is the Zero Level DFD of Computerized Examination System, where we have eloborated the high level process of Examination. It’s a basic overview of the whole Computerized Examination System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Teachers,Questions and Authentication showing the system as a single high-level process, with its relationship to external entities of Exams,Papers and Students. It should be easily understood by a wide audience, including Exams,Students and Teachers In zero leve DFD of Computerized Examination System, we have described the high level flow of the Examination system.

High Level Entities and proccess flow of Computerized Examination System:

  • Managing all the Exams
  • Managing all the Papers
  • Managing all the Students
  • Managing all the Results
  • Managing all the Teachers
  • Managing all the Questions
  • Managing all the Authentication
Zero Level Data flow Diagram(0 Level DFD) of Computerized Examination System

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

First Level DFD (1st Level) of Computerized Examination 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 Computerized Examination System system as a whole. It also identifies internal data stores of ##keyword7##, Questions, Teachers, Results, Students 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 Exams, Students, Questions, ##keyword7##, Teachers 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 Examination.

Main entities and output of First Level DFD (1st Level DFD):

  • Processing Exams records and generate report of all Exams
  • Processing Papers records and generate report of all Papers
  • Processing Students records and generate report of all Students
  • Processing Results records and generate report of all Results
  • Processing Teachers records and generate report of all Teachers
  • Processing Questions records and generate report of all Questions
  • Processing ##keyword7## records and generate report of all ##keyword7##

Second Level Data flow Diagram(2nd Level DFD) of Computerized Examination 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 Computerized Examination System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of ##keyword7##, Questions, Teachers, Results, Students, Papers, Exams.

Low level functionalities of Computerized Examination System

  • Admin logins to the system and manage all the functionalities of Computerized Examination System
