The DFD for Hotel Reservation System is the overall “flow” of data on the project. It is used to document the transformation of data (input-output) for project development.
In addition, the hotel reservation system DFD consists of DFD levels 0, 1, and 2. It also uses entities, processes, and data to define the whole system.
What is Hotel Reservation System DFD?
A DFD for Hotel Reservation System is used for hotel reservation system development it is a data flow which represents the system major business process and alternatives that generate the internal flow of data.
Lastly, we provide a thorough explanation and advanced example of a data flow diagram for hotel reservation system for a better system analysis.
This example emphasizes the three DFD levels (DFD Levels 0, 1, and 2).

Level 0 Data flow diagram for Hotel Reservation System
The context diagram is an alternative name for the Level 0 DFD Diagram for Hotel Reservation System. Users, process management, and data flow make up its parts. Also, the project concept is demonstrated using the single process visualization.
DFD Level 0 shows the entities that interact with a system and defines the border between the system and its environment. This diagram also depicts the hotel reservation system at a high level.
The illustration presents the main process in a single node to introduce the project context. This context explains how the project works in just one look. The user feeds data into the system and then receives the output from it.
Hotel Reservation System Data flow diagram Level 1
The “detonated view” of the context diagram is Hotel Reservation System Data flow diagram Level 1. Its function is to deepen the concept derive from the context diagram.
The designed diagram portrays four different scenarios: customer information management, reservation records management, reservation status monitoring, and transaction management.
Hotel Reservation System Data flow diagram Level 2
Level 2 Data flow diagram hotel reservation system is also the highest abstraction of the data flow diagram. This level also broadens the idea from the DFD level 1. It includes the sub-processes from level 1 as well as the data that flows.
However, not all of the processes in the project must have sub-processes. Only provide this diagram if needed. As long as your previous diagrams were clear and precise, this level is not required.
