This document provides an overview of an airline management system using a database management system. It discusses how the internet has made it easy to book airline tickets and access flight information online. It then describes the basic components of an airline inventory system and the objectives of an airline management system to maximize customer service and provide online booking capabilities. Finally, it outlines some of the key concepts for designing the database system, including entity relationship modeling and normalization.

1. Presentation On
Airline Management System

2. Introduction
 The internet revolution of the late 1990s sharply increased direct
user access to databases.
 Organisations converted many of their phone interfaces to
databases into web interfaces, and made a variety of services
online.
 Therefore, it is very easy to book tickets and find other
information online related to airlines online

3. Types of Inventory
 Raw materials
 Purchased parts and supplies
 Work-in-process (partially completed) products (WIP)
 Items being transported
 Tools and equipment

4.  This document gives a brief discussion on Entity
Relationship in Airline Reservation System, one of
the representative application
particular type can land on a particular airport on the
of Database Management System which is used for
reservations scheduled day

5. Objectives of Airline Management
 Maximize the level of customer service by
providing booking facility.
 It is very easy to book tickets and find other
information online related to airlines online.

6. DBMS Architecture
 It provides a frame work ,which is proposed as
standard by ANSI.
 Three views are
1. External View
2. Conceptual View
3. Internal View

8. External View
Passenger_ id Passenger_name Phone_no
676 Harpreet Sidhu 9897685765
984 Simranjeet Singh 9878654332
Passenger_ id Passenger_name Address
676 Harpreet Sidhu Delhi
984 Simranjeet Singh Chandigarh

9. Conceptual View
Passenger_ id Number
Passenger_ name Text
Address Memo
Phone_no Number
Gender Text

10. Internal View
 It is the view about the actual physical
storage of data .
 This level describes ‘how’ the data will be
actually stored in the database.
 This level serves as a base .

11. Entity Relationship Model
 Entity – It is anything real or abstract about which we
want to store the data .
 Relationship – It specifies the association that
exists between one or more entities.
 Attribute – It is the characteristic which is common to
all or most instances of particular entity.

12. Entity
 Passenger
 Flight
 Time
 Fare
 Ticket
 Location

13. Attributes
 Characteristics of entities
 Domain is set of possible values
 Primary keys underlined

19. Normalization
 It is a process during which redundant relation
schemas are decomposed by breaking up their
attributes in to smaller relation schemas that
possess desirable properties.

2. Second N/F

21. SQL Commands
 It is a simple and powerful language used to create ,access and
manipulate data and structure in the database .
 SQL Statements categorize in to
1. Data Definition Language ( CREATE, DROP, ALTER )
2. Data Manipulation Language (INSERT INTO,UPDATE ,DELETE )
3. Transaction Control Language
4. Query Language ( SELECT)

22. ER-Diagram

23. Data Definition Language
 Define the structure of a database.
Types of DDL commands
 Create
 Alter
 Drop
 Rename

24. Create Command
 The CREATE TABLE statement is used to create a
table in a database.
Syntax Example
 CREATE TABLE table_name
(
column_name1 data_type,
column_name2 data_type,
column_name3 data_type,
....
) ;
CREATE TABLE Passenger
(
PassengerId number primary key,
PassengerName text(20),
Address varchar(50),
Phone _no number(10)
) ;

25. INSERT Command
The INSERT INTO statement is used to insert a new
row in a table.
Syntax
INSERT INTO table_name
VALUES (value1, value2, value3,...)
INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)
OR

26. Example
INSERT INTO Passenger
VALUES (678,‘Harpreet Sidhu’, ‘Delhi', 9889765897);
OR
INSERT INTO Passenger (Passenger_Id, PassengerName)
VALUES (678, ‘Harpreet Sidhu');

27. Alter Command
Syntax
ALTER TABLE table_name
ADD column_name datatype
Example
ALTER TABLE table_name
DROP COLUMN column_name
ALTER TABLE Passenger
ADD DateOfBirth date
ALTER TABLE Passenger
DROP COLUMN DateOfBirth
Example

28. Drop
 The DROP TABLE statement is used to
delete a table
 Syntax
 DROP TABLE table_name
 DROP DATABASE database_name
