Grading Management System Dataflow Diagram

Posted By namita on July 4, 2017

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


Zero Level Data flow Diagram(0 Level DFD) of Grading Management System :

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

High Level Entities and proccess flow of Grading Management System:

  • Managing all the Students
  • Managing all the Examinations
  • Managing all the Marks
  • Managing all the Evaluations
  • Managing all the Papers
  • Managing all the Grades
  • Managing all the Login
Zero Level Data flow Diagram(0 Level DFD) of Grading Management System

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

First Level DFD (1st Level) of Grading 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 Grading Management System system as a whole. It also identifies internal data stores of Login, Grades, Papers, Evaluations, Marks that must be present in order for the Grading system to do its job, and shows the flow of data between the various parts of Students, Marks, Grades, Login, Papers 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 Grading.

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

  • Processing Students records and generate report of all Students
  • Processing Examinations records and generate report of all Examinations
  • Processing Marks records and generate report of all Marks
  • Processing Evaluations records and generate report of all Evaluations
  • Processing Papers records and generate report of all Papers
  • Processing Grades records and generate report of all Grades
  • Processing Login records and generate report of all Login

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

DFD Level 2 then goes one step deeper into parts of Level 1 of Grading. It may require more functionalities of Grading to reach the necessary level of detail about the Grading functioning. First Level DFD (1st Level) of Grading Management System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Login, Grades, Papers, Evaluations, Marks, Examinations, Students.

Low level functionalities of Grading Management System

  • Admin logins to the system and manage all the functionalities of Grading Management System
  • Admin can add, edit, delete and view the records of Students, Marks, Papers, Login
  • Admin can manage all the details of Examinations, Evaluations, Grades
  • Admin can also generate reports of Students, Examinations, Marks, Evaluations, Papers, Grades
  • Admin can search the details of Examinations, Papers, Grades
  • Admin can apply different level of filters on report of Students, Evaluations, Papers
  • Admin can tracks the detailed information of Examinations, Marks, Evaluations, , Papers

Grading System ER Diagram

Posted By freeproject on July 17, 2017

This ER (Entity Relationship) Diagram represents the model of Grading System Entity. The entity-relationship diagram of Grading System shows all the visual instrument of database tables and the relations between Examinations, Papers, Students, Result etc. It used structure data and to define the relationships between structured data groups of Grading System functionalities. The main entities of the Grading System are Students, Examinations, Marks, Papers, Grades and Result.

Grading System entities and their attributes :

  • Students Entity : Attributes of Students are student_id, student_college_id, student_name, student_mobile, student_email, student_username, student_password, student_address
  • Examinations Entity : Attributes of Examinations are exam_id, exam_student_id, exam_roll_number, exam_date exam_name, exam_type, exam_description
  • Marks Entity : Attributes of Marks are mark_id, mark_student_id, mark_exam_id, mark_result, mark_number, mark_type, mark_description
  • Papers Entity : Attributes of Papers are paper_id, paper_exam_id, paper_subject, paper_time paper_name, paper_type, paper_description
  • Grades Entity : Attributes of Grades are grade_id, grade_student_id, grade_name, grade_type, grade_description
  • Result Entity : Attributes of Result are result_id, result_student_id, result_date, result_type, result_description

Description of Grading System Database :

  • The details of Students is store into the Students tables respective with all tables
  • Each entity (Result, Marks, Grades, Examinations, Students) contains primary key and unique keys.
  • The entity Marks, Grades has binded with Students, Examinations entities with foreign key
  • There is one-to-one and one-to-many relationships available between Grades, Papers, Result, Students
  • All the entities Students, Grades, Marks, Result are normalized and reduce duplicacy of records
  • We have implemented indexing on each tables of Grading System tables for fast query execution.
