Railway Management System Data flow diagram is often used as a preliminary step to create an overview of the Railway without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Railway process. It contains all of the userflow and their entities such all the flow of Trains, Timetable, Fare, Stations, Booking, Customers, Ticket. All of the below diagrams has been used for the visualization of data processing and structured design of the Railway process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Railway Management System :
This is the Zero Level DFD of Railway Management System, where we have eloborated the high level process of Railway. It’s a basic overview of the whole Railway Management System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Booking,Customers and Ticket showing the system as a single high-level process, with its relationship to external entities of Trains,Timetable and Fare. It should be easily understood by a wide audience, including Trains,Fare and Booking In zero leve DFD of Railway Management System, we have described the high level flow of the Railway system.High Level Entities and proccess flow of Railway Management System:
- Managing all the Trains
- Managing all the Timetable
- Managing all the Fare
- Managing all the Stations
- Managing all the Booking
- Managing all the Customers

First Level Data flow Diagram(1st Level DFD) of Railway Management System :
First Level DFD (1st Level) of Railway Management System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Railway Management System system as a whole. It also identifies internal data stores of Ticket, Customers, Booking, Stations, Fare that must be present in order for the Railway system to do its job, and shows the flow of data between the various parts of Trains, Fare, Customers, Ticket, Booking of the system.

Second Level Data flow Diagram(2nd Level DFD) of Railway Management System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Railway. It may require more functionalities of Railway to reach the necessary level of detail about the Railway functioning. First Level DFD (1st Level) of Railway Management System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Ticket, Customers, Booking, Stations, Fare, Timetable, Trains.Low level functionalities of Railway Management System
