The DFD (Data Flow Diagram) for Online Movie Ticket Booking System describes the overall “flow” of data on the project. It is used to document the transformation of data (input-output) for project development.
The online movie ticket booking system DFD consists of DFD levels 0, 1, and 2. It also uses entities, processes, and data to define the whole system.
The table shows the overview and details of the data flow diagram (DFD) for online movie ticket booking system. It has complete information about the project.
0 Level DFD for Online Movie Ticket Booking System
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.
In addition to this, you will perceive through the diagram that there is already the presence of data flow. Though the process is very general, the flow of data is clear. Nevertheless, just modify this diagram to meet the other requirements and include other matters regarding movie ticket booking.
The “detonated view” of the context diagram is Online Movie Ticket Booking DFD Level 1 . Its function is to deepen the concept derive from the context diagram.
Specifically, level 1 shows the broader details of Online Movie Ticket Booking System DFD Level 0. This is to clarify the paths (flow) of data and its transformation from input to output. 1 Level DFD for Online Movie Ticket Booking System
The designed diagram portrays four different scenarios: customer information management, booking records management, booking status monitoring, and transaction management.
Firstly, the flow of data starts from the ticketing personnel and buyers. Then the system caters to the transaction. This idea was based on ticket booking processes or transactions.
You can also see the data store used or the database. The database is also used in storing users’ data inputs. Then it serves as the source of outputs.
Level 2 DFD for Online Movie Ticket Booking 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.
2 Level DFD for Online Movie Ticket Booking System
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.
You can add more to this and it is up to you how will you create your data flow diagram. Also, consider the data flow included and be precise with your information.

To define the data flow diagram, we used DFD notations. They were presented in symbols to be understood easily. The symbols present the following:
These data flow diagram notations represent the total data handling. Using these Data Flow Diagram symbols would also help to draw attention to the system’s architecture in a simpler way.
Time needed: 5 minutes
Data flow diagrams show how information moves through a system or process. Along with data repositories and users, it also includes data inputs and outputs. Before you construct the actual diagram, you must be familiar with its symbols and applications.
Analyzation is very important in creating a data flow diagram. It also helps in understanding the meaning of the diagram and avoiding unwanted errors.
The gathered information from the users is very useful in creating the diagram. You also need to evaluate the data and choose the general processes.
To plot the data flow diagram, you will need the users, processes, databases, and data flows. Then you’ll base the data flow on the evaluated information to have a detailed data flow diagram.
First, you need to identify the users involved and the main processes they will perform. This will first generate the DFD Level 0, or the context Diagram.
Then you will deepen the idea in DFD Level 0. To perform this, you will need to figure out the sub-processes that complete the main process. You will also add a data store that will serve as storage for the processed data.
After that, you will trace the flow or path of data to know the transformations of data inputs into outputs. This will create the DFD Level 1.
In conclusion, we have discussed the things that we need to know to create a data flow diagram. Its main purpose is to emphasize the transformation of data from input to output. Along with this, DFD levels were very useful in elaborating the system.
Further, the information was appropriately categorized. It highlights the online movie ticket booking system’s organizational structure. This documentation will not only help with the foundation of the project but also with its behavior. Check out these recommended and related articles for more!
