Posted By freeproject on April 18, 2017

Railway Reservation System Data flow diagram is often used as a preliminary step to create an overview of the Railway Reservation without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Railway Reservation process. It contains all of the userflow and their entities such all the flow of Trains, Booking, Ticket, Train Shedule, Train Route, Customer, Payment. All of the below diagrams has been used for the visualization of data processing and structured design of the Railway Reservation process and working flow.


Zero Level Data flow Diagram(0 Level DFD) of Railway Reservation System :

This is the Zero Level DFD of Railway Reservation System, where we have eloborated the high level process of Railway Reservation. It’s a basic overview of the whole Railway Reservation System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Train Route,Customer and Payment showing the system as a single high-level process, with its relationship to external entities of Trains,Booking and Ticket. It should be easily understood by a wide audience, including Trains,Ticket and Train Route In zero leve DFD of Railway Reservation System, we have described the high level flow of the Railway Reservation system.

High Level Entities and proccess flow of Railway Reservation System:

  • Managing all the Trains
  • Managing all the Booking
  • Managing all the Ticket
  • Managing all the Train Shedule
  • Managing all the Train Route
  • Managing all the Customer
  • Managing all the Payment

First Level Data flow Diagram(1st Level DFD) of Railway Reservation System :

First Level DFD (1st Level) of Railway Reservation 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 Reservation System system as a whole. It also identifies internal data stores of Payment, Customer, Train Route, Train Shedule, Ticket that must be present in order for the Railway Reservation system to do its job, and shows the flow of data between the various parts of Trains, Ticket, Customer, Payment, Train Route of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Railway Reservation.

Main entities and output of First Level DFD (1st Level DFD):

  • Processing Trains records and generate report of all Trains
  • Processing Booking records and generate report of all Booking
  • Processing Ticket records and generate report of all Ticket
  • Processing Train Shedule records and generate report of all Train Shedule
  • Processing Train Route records and generate report of all Train Route
  • Processing Customer records and generate report of all Customer
  • Processing Payment records and generate report of all Payment

Second Level Data flow Diagram(2nd Level DFD) of Railway Reservation System :

DFD Level 2 then goes one step deeper into parts of Level 1 of Railway Reservation. It may require more functionalities of Railway Reservation to reach the necessary level of detail about the Railway Reservation functioning. First Level DFD (1st Level) of Railway Reservation System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Payment, Customer, Train Route, Train Shedule, Ticket, Booking, Trains.

Low level functionalities of Railway Reservation System
