ABSTRACT

This term contains Introduction to the Railways reservation system .It is the computerized system of reserving the seats of train seats in advanced . It is mainly used for long root . On-line reservation has made the process for the reservation of seats very much easier than ever before. In our country India, there are number of counters for the reservation of the seats and one can easily make reservations and get tickets.

Then this term paper contain entity relationship model diagram based on rail reservation system and introduction to relation model .There is also design of the database of the rail reservation system based on relation model. Relation model has three relation RAIL_DETAILS , C_DETAILS and RESERVATION. Example of some SQL queries to retrieves data from rail management database.

RAILWAY MANAGEMENT SYSTEM :- railway management System is the computerized system of reserving the seats of train seats in advanced . It is mainly used for long

root . On-line reservation has made the process for the reservation of seats very much easier than ever before. In our country India, there are number of counters for the reservation of the seats and one can easily make reservations and get tickets. Almost all of the manual reservations centres have been converted into computerized reservation centers, which provide booking and reservation of the ticket facilities from one station to another. This system is very helpful and it is very easy to operate on it. It allows advanced booking.

Computerization system has also made it possible for passengers to book their tickets online and it has also allowed for the checking whether the tickets in waiting list are confirmed or not. It also provides the information regarding fares and timings of the train. An emergency reservation scheme has also been provided by this computerized system.

In the train reservation system for a state transport we should have all the details of cities, villages etc to design the database of this system. For this system we have to design the database which have all the information about trains their timing, origin, destination, Roots, Total no. of seats in a particular train. Type of train and the full detail of the passenger for example passenger id , passenger name, phone number, address, seats the passenger wants to reserve etc.

Represention of Train Reservation System for a state transportation with the help of Entity- Relationship Diagram and Relational Model.

In this diagram CUSTOMER , TRAIN and RESERVATION are entities and the relationship between them is reserves.

Passenger entity has seven attributes :- C_No, Ph_No , C_Name, Add, Age,Sex,State which defines customer number, phone number, customer name,

address, age ,sex and State of customer.

Train entity has eight attributes :- Origin, Destination, T_seats, , T_type , T_no ,T_Timing mean departure time and arrival time of the train. Fair/perseat which defines origin of train, destination of train, total no. of seats in a train, train type and train number,timing of train,fair of reservation for per seat.

RESERVATION relation has five attribute:- R_Date ,Seats_reserved,CID, Receipt_No,BNO. which defines reservation date , number of seats reserved by passenger,passenger id, Receipt no. given to the customer, train number.

RELATIONAL MODEL:-

train- Details Table :

Firstly, we create a table using CREATE query. Different attributes are defined with data types. Here T_NO is a primary key.

Then we insert values of all the attributes into this table using INSERT SQL query

Select query is used to retrieve data from the relation.

Primary Key

T_Type T_No Origin Destination T_SEATS Departure Time

Relation named train_Details is created which stores the information about train.

2) C-Details Table:

This table give the all the details of the passenger. in this table C_ID is the primary key so that there is no duplicacy of the passenger .

We have to create another table passenger using CREATE query

To retrieve the passenger table we again apply Select statement.

Relation named RESERVATION is created which stores the information about reservation of train

In this relation T_No act as a foreign key references from train_details.

Cancelation of TICKET or Reaervation:- If any passanger wants the cancelation of his tickets or reservation then the deletion of this particular reservation record from database is done using DELETE SQL query.
