DFD for Bus Reservation System (Data Flow Diagram)

The DFD for Bus Reservation System is the visualization of data processing on the project. It is used to document the transformation of data (input-output) of the project development.

In addition, The bus reservation system DFD consists of levels 0, 1, and 2. Each level is composed of Entities, processes, and data.

What is a Bus Reservation System?

The bus reservation system is a system which assists bus companies in providing quality services for their passengers. It helps businesses process booking records and bus management in one place. Therefore the system is a must-have for bus company owners.

What is Bus Reservation System DFD?

One of the methods used for bus system development is the DFD (data flow diagram). It represents the system’s major processes and alternatives that generate the internal flow of data to bus ticketing.

Importance of Data Flow Diagram (DFD)

The importance of the data flow diagram (DFD) is to show the actual happenings in the system. This is done by visualizing the system’s data management at various levels.

Furthermore, the DFD levels were used to discuss the bus reservation system data flow. These levels have their part in expounding the system’s data flow structure details. It is then applied in creating Bus Reservation System ER Diagram.

Bus Reservation System Data Flow Diagram (DFD)

A thorough explanation is provided for the example data flow diagram for bus reservation system. This example emphasizes the three DFD levels (DFD Levels 0, 1, and 2).

0 Level DFD for Bus Reservation System

The DFD Level 0 (context diagram) purpose is to demonstrate the project concept using a single process.

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 bus 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.

Level 1 DFD for Bus Reservation System

The “detonated view” of the context diagram is Bus Reservation System DFD Level 1. Its function is to deepen the concept derive from the context diagram.

Level 1 DFD clarifies the paths (flow) of data and its transformation from input to output.

The designed diagram portrays four different scenarios. customer information management, order or reservation management, scheduling of deliveries, and transaction and payments management.

Level 2 DFD for Bus Reservation System

Bus Reservation System Level 2 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.

Data Flow Diagram Notations:

To define the data flow diagram, we used DFD notations. They were presented in symbols to be understood easily. The symbols present the following:

• External Entity: provides or receives information and communicates with the system. They are the origins and destinations of data entering and exiting the system. Entities could also be a third-party company or individual, a computer system, or a business system. The terms used for entities are terminators, sources, sinks, and actors.
• Process: is the part of DFD that modifies data and generates an output. It also executes calculations, sorts data according to logic, or directs data flow according to business standards.
• Data Store: A database table or a membership form are examples of files or repositories that store information for later use. Also, this part requires proper labeling.
• Data Flow: is the path that the data takes between external entities, processes, and data repositories. It depicts the interface between the other components. Also, a labeled arrow is used to present data flow.

Conclusion

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.
