Hotel Management System DFD (Data flow diagram) is often used as a first step to get a general picture of the system without going into too much detail, which can later be expanded on.
In most cases, this is the overall data flow and processes of the Hotel Management process where in the application.
The Data Flow Diagram is composed of Levels 0, 1, and 2 that explain the data handling of the Hotel 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 principal function.

What is DFD of Diagram Hotel Management System
This DFD of Hotel Management System represents the flow of data and the transformations in the form of DFD Level 0, 1 and 2. These transformations occurs as data enters and exits in a system. In the DFD, input, processing, and output are used to represent and define the overall system.
A data flow diagram is a graphical view of how data is processed in a system in terms of input and output. The Data flow diagram (DFD) contains some symbol for drawing the data flow diagram.
Importance of Hotel Management System DFD (Data Flow Diagram)
The Importance of Hotel Management System DFD (Data Flow Diagram) is that it helps the audience in understanding what is happening in the system. Also how the system manages its data at different levels of detail.
It is one of the methods use for development. It represents the system’s major processes, and alternatives that generate the flow of data within the system.
Moreover, the data includes in Data Flow Diagram labeled properly to guide the developers on the structure of the Hotel Management System.
The DFD Level 2 was chosen as the highest abstraction level because it contains all the information required to complete the System Data Flow Diagram. The diagrams then show how to build the system in terms of data handling.
How to Create Hotel Management System DFD level 0 1 2
Time needed: 5 minutes
Here is an example on how to create a Hotel Management System level 0 1 2
- DFD level 0 diagram for Hotel Management System
The DFD Level 0 diagram for Hotel Management System is also known as the context diagram of the system.
The level 0 or context diagram presents the main idea as the basis for the subsequent levels. The basic idea is represented by a single process consisting of the main process, users, and data.
- Example of DFD level 1
These level 1 diagram shows how data flows through the system. In addition to, its content comes from the previous level, which helps you understand the main process of the Hotel Management System even more. In DFD level 1, the diagram also shows more information about how processing works.
- Hotel Management System DFD Level 2
DFD level 2 comes next after level 0 and 1. But creating the DFD Level 2 has two things to think about.
DFD Level 2 should show all the processes and data in a more detailed way than level 1. As a result, it should also show the databases that are used.
This diagram shows you the database that stores all the information you need to finish the whole Hotel Management System process.
Furthermore, the main goal of DFD Level 2 is to show where all the data flows through the hotel management system comes from and go to. Lastly, it is to show programmers on the project how the data flows inside it.
Conclusion:
It is very important for you to know the diagrams that used to design and build the Hotel 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,
