E-Learning Management System Dataflow Diagram

Posted By freeproject on April 20, 2017

E-learning Management System Data flow diagram is often used as a preliminary step to create an overview of the E-learning without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the E-learning process. It contains all of the userflow and their entities such all the flow of Student, Activity Log, Assignment, Files, Teacher, Subject, Teacher. All of the below diagrams has been used for the visualization of data processing and structured design of the E-learning process and working flow.


Zero Level Data flow Diagram(0 Level DFD) of E-learning Management System :

This is the Zero Level DFD of E-learning Management System, where we have eloborated the high level process of E-learning. It’s a basic overview of the whole E-learning Management System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Teacher,Subject and Teacher showing the system as a single high-level process, with its relationship to external entities of Student,Activity Log and Assignment. It should be easily understood by a wide audience, including Student,Assignment and Teacher In zero leve DFD of E-learning Management System, we have described the high level flow of the E-learning system.

High Level Entities and proccess flow of E-learning Management System:

  • Managing all the Student
  • Managing all the Activity Log
  • Managing all the Assignment
  • Managing all the Files
  • Managing all the Teacher
  • Managing all the Subject
  • Managing all the Teacher

First Level Data flow Diagram(1st Level DFD) of E-learning Management System :

First Level DFD (1st Level) of E-learning 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 E-learning Management System system as a whole. It also identifies internal data stores of Teacher, Subject, Teacher, Files, Assignment that must be present in order for the E-learning system to do its job, and shows the flow of data between the various parts of Student, Assignment, Subject, Teacher, Teacher 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 E-learning.

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

  • Processing Student records and generate report of all Student
  • Processing Activity Log records and generate report of all Activity Log
  • Processing Assignment records and generate report of all Assignment
  • Processing Files records and generate report of all Files
  • Processing Teacher records and generate report of all Teacher
  • Processing Subject records and generate report of all Subject
  • Processing Teacher records and generate report of all Teacher

Second Level Data flow Diagram(2nd Level DFD) of E-learning Management System :

DFD Level 2 then goes one step deeper into parts of Level 1 of E-learning. It may require more functionalities of E-learning to reach the necessary level of detail about the E-learning functioning. First Level DFD (1st Level) of E-learning Management System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Teacher, Subject, Teacher, Files, Assignment, Activity Log, Student.

Low level functionalities of E-learning Management System

  • Admin logins to the system and manage all the functionalities of E-learning Management System
  • Admin can add, edit, delete and view the records of Student, Assignment, Teacher, Teacher
  • Admin can manage all the details of Activity Log, Files, Subject
  • Admin can also generate reports of Student, Activity Log, Assignment, Files, Teacher, Subject
  • Admin can search the details of Activity Log, Teacher, Subject
  • Admin can apply different level of filters on report of Student, Files, Teacher
  • Admin can tracks the detailed information of Activity Log, Assignment, Files, , Teacher
