  • It could be one of the best elearning platforms for any e-learning content development company to publish his content.E – LMS ecommerce integration can be done to make this a commercial learning application for everyone.

Level 0 DFD for E-Learning Management System

Level 0 DFD is also known as context level DFD. Level 0 DFD or context diagram for the E Learning management system represents the entire system as a single process and its relationship with external entities. This is basically an overview of the organizational system that shows the system boundaries, external entities and its interaction with the system.

There are two external entities in this context DFD:

  • Student
  • Admin

Level 1 Data Flow Diagram for E-Learning Management System

Level 1 data flow diagram is also a general overview of the proposed system but it goes into more detail than a context diagram. Level 1 DFD for the E-Learning system breaks the single process into the main sub processes. E-Learning system has following sub process in its level 1 DFD:

Student Registration: Student registration process stores and maintains records of all the students. When a new student registers on the elearning platform, this process receives his details and store them in the database. This process takes all the program information that are currently being run by the organization. This process makes a master record of student information. This process also sends this information to other processes as required.

E-Learning Curriculum: E-Learning Curriculum process maintains a curriculum of different programs that are being run by the organization. Admin can add new program details or edit any existing program.Each program is divided into several modules. Admin can also upload video tutorials and question and answer of all the modules.

E-Learning Activity: E-Learning activity is a process for checking the learning progress of each student through online examination. This process takes student information from the Student Registration process, module and question information from the E-Learning Curriculum process.

Admin can upload video tutorials of different modules. Students can access these video lectures according to their program and learn.

Level 2 Data Flow Diagram for E-Learning Management System

Level 2 data flow diagram further breaks the level 1 process into smaller sub processes. This level also adds information about datastores.

In this level 2 DFD of E-Learning system the “E-Learning Activity” process is further divided into

  • Online Examination
  • Video Tutorial & Questions

E-Learning Curriculum” is further divided into

  • E-Learning Program
  • E-Learning Module

Here is short description about all 4 sub processes

Online Examination: As the name indicates, this sub process is for taking online examinations of students. Admin schedules date and time of different program’s online examination. Students can login their user id and participate in the examination. This process sends certificates to the students.

Video Tutorial & Questions: Video Tutorial & Questions sub process handles record of all the video tutorials and related question answers. These video lectures can be accessed by the students. Students can also answer short questions asked at the end of each lecture.

E-Learning Program: E-Learning Program handles records of all the programs run by the organization. Admin can add new program information or edit any existing program detail.

E-Learning Module: Each program has several modules. This process handles records of all the modules. This information is also sent to the Online Examination process.
