Online Railway ticket reservation is very useful nowadays. This is very important to design a good-working system software for ticket booking and related transactions. To design it, full-track documentation of models(ER, DFD, Class, Use-case, Activity, Sequence) is required as per as software development is concerned. 

Features of the System:

The Reservation system should contain the following features: 

  1. If a passenger wants to reserve ticket(s), firstly, he/she has to log in to the Railway system with valid credentials. Then, the passenger has to provide his/her details with the date of the journey, names of the passengers and their details, origin station details, destination station details, and the class type of the required ticket(s).
  2. The Railway Reservation System will provide the available Train-list, and Seat-availability, via-details.
  3. To book a ticket passengers can pay through online/offline mode. After successful payment of the ticket fare the System will generate the ticket and PNR no. will be given to the passenger. The System also keeps the payment details and sends them to the system Admin.
  4. The Passenger can check PNR status (confirmed, RAC, waiting list) by entering the PNR no. into the Reservation system.
  5. The Reservation system should store all train details, fare details (by zone, class, and date wise), PNR no, date of trains, etc. This maintenance should be controlled by the Admin. 
  6. The System also has refund rules which have a date of reservation, ticket fare, and refundable percentage. The passenger can simply cancel the ticket(s) by entering the PNR no and a cancel ticket request. After cancelation, the Admin will pass the refundable amount to the System and the System will give the refundable amount to the passenger.

Required Diagrams:

Entity Relationship(ER) Diagram:  

ER diagram displays the relations between the various entities(classes and their attributes) stored in the database.  ER diagrams are very important for any database project. This diagram shows the communication between entities and their attributes.

ER Diagram for Online Railway Ticket Reservation System

 

The above ER diagram illustrates the key information about the railway reservation system, including entities like PAX_info, Login_credentials, Ticket_reservation, refund_rule, via_details, train_fare, Train, Seat_availability, Class, Zone, station, pay_info. This diagram also shows the relationships between entities.

Entities and their attributes are:

PAX_info: Attributes of PAX_info entity are  Passenger_id  (primarykey) ,SRL_no ,PAX_name ,PAX_age ,PAX_sex ,fare,seat_no.

  • Login_credentials: Attributes of Login_credentials entity are login_id(PK) , password.
  • Ticket_reservation: Attributes of Ticket_reservation entity are PNR_no(pk),to-date, from-date, to-km, from-km, to-station, from-station, Train_code.
  •  Refund_rule: Attributes of  refund_rule entity are to-time, from-time, refundable-amt.
  • via_details: Attributes of via_details entity are Details_id(PK), Train_code, via_station_code, km_from_origin, Reach_time.
  • train_fare: Attributes of train_fare entity are to-date, from-date, to-km, from-km, Fare, Class_id.
  • Train: Attributes of Train entity are Train_code(PK), Distance, Train_name, Start_time, End_time, Start_station_code, End_station_code, Frequency.
  • Seat_availability: Attributes of Seat_availability entity are Train_code, Class_code, and Number of seats.
  • Class: Attributes of Class entity are Class_id(PK), coach_prefix, class_code, Class_name, seat_per_coach.
  • Zone: Attributes of Zone entity are zone_id(PK), Zone_name,Zone_code.
  • Station: Attributes of station entity are Station_id(PK),Station_code,station_name, zone_id.
  • Pay_info: Attributes of Pay_info entity are payment_id(PK), pay_mode, amount, pay_date, srl-no, PNR_no, inst_type, inst_amt.

Relationships between Entities:

  • One-to-one relation: PAX_info to login_credentials , PAX_info to refund_rule, Train to Via_details, Class to train_fare, PAX_info to pay_info.
  • Many-to-one relation: PAX_info to ticket_reservation, Zone to the station, Class to seat_availability.
  • Many-to-many: Train to the station, Train to class.
