Hi there Itsourcecoders! Today I will give you ideas about the Best Data Flow Diagram (DFD levels) for Hotel Management System 2021. This knowledge will also give you deep understanding about Hotel management system DFD levels 0, 1 and 2. The discussion will teach you in managing Hotel information as well as the flow of activities happens in hotel management system.
Here’s what you need to know.
In the DFD, input, processing, and output are used to represent and define the overall system.
Watch the video here to see the full discussion of Hotel Management System DFD Level 0 1 2 | Best Data Flow Diagrams 2021
The following are the flows that the Hotel Management System can generate:

Time needed: 10 minutes.
Here’s the Dataflow Diagram levels 0 1 2 for Hotel Management System and step-by-step way on how to create a Hotel management system DFD.
- DFD for Hotel Management System Level 0
To start with, let us familiarize what is Hotel management system level 0.
The hotel management system level 0 is also known as context diagram. It’s supposed to be an abstract view, with the mechanism represented as a single process with external parties.
This DFD for the system depicts the overall structure as a single bubble. It comes with incoming/outgoing indicators showing input and output data.
In this data flow diagram you will see the general process done in Hotel management. This will also serve as a guide as you go through the deeper processes of the Hotel management system data flow diagrams.
As you see, when you build the levels of data flow diagrams, the connections of the transactions and data also broadens and gets more specific.
- DFD for Hotel Management System Level 1
Next to the context diagram is the level 1 data flow diagram.
The content of Hotel management system DFD level 1 must be single process node from the context diagram and is broken down into sub processes
In this level, the system must display or reveal further processing information. And the actors that are going to use this system were the customers , hotel administrator and the hotel employees.
The following are essential data to accommodate:
• Customer Information
• Employees Information
These procedures require information such as a list of customers, rooms, employees and facilities from which served as the bases for admin to manage hotel transactions. This type of data is represented by a data store.
With being knowledgeable about the DFD level 1 of the Hotel Management System, you will know then its broaden context terms.
In addition to that, this may also serve as your reference on how the inputs or data fed on the system. Then you will be also informed about the outputs that the system gives.
These processes shown in the DFD were all based on the concept of Hotel Management System.
- DFD for Hotel Management System Level 2
After presenting the Hotel management system DFD levels 0 and 1, next to that is level 2.
Here’s what you need to consider in creating data flow diagram level 2 for Hotel management system.
• The Level 2 DFD for the system should represent the basic modules as well as data flow between them.
• Since the DFD level 2 is the highest abstraction level, its Hotel management system processes must be detailed that is based on the DFD level 1.
Finally, after figuring the processes given in the system, the user will now have their request being processed.
The Processes that the system should prioritize are as follows:
• Managing Clients
• Assigning Rooms
• Managing Employees
• Facilitates Reservation
• Manage Transactions
DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Hotel management system. Considering the the dataflow levels mentioned above, you can determine well the importance of breaking the processes into more specific manner.
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 will also be your references as you make your own management system DFD levels 0, 1 and 2.
Additional Knowledge on DFD Levels 0 1 2 of Hotel Management System
What is Hotel Management System DFD level 0?
DFD level 0 is also known as context diagram. With the mechanism represented as a single process and external parties it will be an abstract view. It depicts the overall structure as a single bubble with incoming/outgoing indicators showing input and output data.
The data flow diagram level 0 also considers the entire system to be a single process and emphasizes the system’s interaction with external entities.
Context diagrams (level 0 DFDs) are diagrams in which the entire system is represented as a single process.
A single process node and its connections to external entities are depicted in Level 0 data flow diagrams.
What does a Hotel Management System level 1 DFD entail?
Level 1 DFDs provide a broad overview but go into greater depth than a context diagram. The single process node from the context diagram is broken down into sub processes in a level 1 data flow diagram.
The System level 1 DFD lists all of the major sub-processes that make up the entire system. A level 1 DFD can be thought of as a “detonated view” of the context diagram.
A single production node and its relationships to external entities are depicted in Level 0 data flow diagrams. Level 1 DFDs provide a broad overview but go into greater depth than a context diagram.
The single process node from the context diagram is broken down into sub processes in a level 1 data flow diagram.
What does a Hotel Management System level 2 DFD entail?
The 2-level DFD delves even deeper into the concepts of 1-level DFD. It can be used to plan or record all of the specific/necessary information about how the system works.
Level 2 DFD is the DFD’s highest abstraction level and represents the system’s basic modules as well as data flow between them.
