DFD for College Management System

DFD for College Management System are frequently used as a preliminary step to create an overview of software without going into great detail, which can then be elaborated. It typically consists of overall application dataflow and College Management processes.

The Data Flow Diagram is composed of Levels 0, 1 and 2 that explains the data handling of College Management System. In addition, it also acts as the foundation for subsequent Levels and DFD Level 1 extends DFD Level 0 and DFD Level 2 includes databases for all data used in the project’s function.

What is DFD for College Management System

The DFD (Data Flow Diagram) of College Management System depicts the overall of flow of data inside the system. Its focus is in the movement of data that enters and exits the system.

Data Flow Diagram is graphical representation of flow of data through system and used for visualization. College Management System Data Flow Diagram comes with three major levels which were the level 0 (context diagram), level 1, and level 2.

WHY DFD for College Management System IS IMPORTANT ?

The most important function of DFD for College Management System data flow diagram is to organize the program. Programmers used Data flow diagram plan out exactly how their new program will accomplish its goal.

The Data Flow Diagram Levels has their roles in emphasizing the College Management System Data Flow Diagram. The Level 0 or Context Diagram presents the single and main process of College Management System as well as the main users and the data, whereas the Data Flow Diagram Level 1 and 2 portrays specific process and sub processes and the detailed movement of data.

0 level DFD for College Management System

This is the Zero 0 Level DFD of College Management System, where we have elaborated the high level process of the system. The level 0 diagram displays the abstract view of the system or the single process with its external parties.

Context diagram represents the system’s general process with external entities into single node. It depicts the overall structure with labeled arrows indicating the input and output data. Its illustration shows the main process (represented by a box), the external entities and the data flow inside the system.

It represents the overall structure as a single bubble with incoming/outgoing indicators that display input and output data. This is the main idea that reveals the main process, users, and data that circulates throughout the system.

1 level DFD for College Management System

 First Level DFD (1st Level) of College Management System shows how the application is divided into sub-systems (processes), each of which deals with one or more data flows. Its’ content is derived from the context diagram and is broken down into sub processes.

This is to let the programmer know what are the included processes and data inputs are included on the system. The broaden context terms with being knowledgeable about the DFD level 1.

This also serve as the reference on how the system manages the inputs or data fed on the college management system. You’ll also be inform about the outputs that the system gives. And the processes shown here were all based on the concept of College Management System.

How to draw a DFD for College Management System

Time needed: 5 minutes.

Here how to draw DFD for College Management System Project. It is data flow diagram which is a graphical view of how data is processed in a system in terms of input and output.

  1. Context Diagram

    In this data flow diagram you will see the general process done in College management system. You can see the main function of the project, it primary users (external entities) and data flow (labeled arrows).

    COLLEGE MANAGEMENT SYSTEM DFD LEVEL 0

  2. College Management System DFD Level 1

    You’ll see in the illustration that the data processes and flow broadens while the external entities stays the same. That is because the revealed external entities were the targeted users when the project is done.
    COLLEGE MANAGEMENT SYSTEM DFD LEVEL 1

  3. DFD for College Management System Level 2

    The presented level not only shows you the detailed processes of system, but also gives you precise destination of the data that flows in the system. This DFD diagrams will also be your references as you make your own College management system DFD levels 0, 1 and 2.
    COLLEGE MANAGEMENT SYSTEM DFD LEVEL 2

Conclusion:

It is very important for you to know the diagrams that used to design and build the College Management System. That is to help you build a fully-functioning system with the help of DFD, so that you can use it. Creating a DFD will help you see what inputs and outputs the system needs to process and transform. Not only that, but you can also connect its diagram to other diagrams,
