The document provides a comprehensive overview of database management systems (DBMS) and their application in an airline management system, highlighting the benefits, implementation steps, and data organization through ER diagrams and SQL. It emphasizes the efficiency, data independence, and security advantages of using DBMS while also addressing potential issues such as data duplication. Additionally, it outlines required entities and their attributes relevant to the airline industry, as well as basic SQL commands for data manipulation.

Data store in table,Rows
And Column

Database management:-
 A database management system (DBMS) is
system software.
 Creating and managing databases.
 In which files are integrated to each other
 The DBMS facilitates the user to create,
 retrieve, update and manage data.
Importance of DBMS:-
 It helps make data management more efficient
and effective.
 A database management system stores, organizes
and manages a large amount of information
within a single software application.
 Use of this system increases efficiency of business
operations and reduces overall costs.

Introduction of Airline Managements System:-
 We used DBMS in airline management system.
 First of all, we need to identify the entities, attribute
and relationships.
 When we use DBMS, the record of all airport
management entities is in the same location.
 We shows entities, attributes and relationships by ER
diagram.
 SQL is a language which is used for applying queries.
Example we applying queries for insertion, deletion or
updating etc.
Benefits:-
 While using DBMS, the data is independent.
 It removes duplication of data.
 Easy to insert, update and delete data in DBMS.
 When we use DBMS, the files integrated each other.
 We can secure our data by using DBMS.

5. 5
Problems:-
 They do not communicate at accurate time.
 Duplication of Data
 Data Dependency
 At the Time of installation of a data base or
implementation of database we check the capacity of
the operating system if operating system cannot
capable to perform the operations we need to install
a upgrade operating system to run a database
efficiently.
Implement of DBMS:-
 Analyze user environment.
 Develop logical model.
 Choose DBMS.
 Map logical model DBMS.
 Develop physical Design.
 Evaluate Physical Model.

Requirements of DMS:-
 Database management system required an operating system that
has capability to run and perform the operation of database with
the help of quires.
 Database required a that Database Administrator for control the of
the data flow.

Entities & Attribute:-
 ENTITY: Airport
Attribute (Airport_id,Airport_name,city)
 ENTITY: Employee
Attribute (emp_id, emp_name,emp_age,Airport_name,
Salary,job,emp_address)
 ENTITY: Passengers
Attribute(p_id,p_name,p_age,p_adress,country_name )
 ENTITY: Airline Companies
Attribute (c_id,c_name,city,country)
 ENTITY: Ticket
Attribute (order_no,flight_name,seat_dass,price,
passenger_name)
 ENTITY: flight time
Attribute (flight_no,airport_name,arrivals_hours,
airport_arrival,departure_hours)

9. 9
Description:-
 Airport has employees
 Employees serve passengers
 Passengers purchases tickets
 Flight carries passengers
 Ticket belongs to flight
SQL:-
 S.Q.L stands for Structured Query language.
 It is used to interact with the database.
 SQL was developed by IBM.
 It is the standard language for RDBMS.
 Using SQL statements we can perform tasks such as retrieving or
updating data from the database.
 Select statement
 Insert into
 Delete table

10. 10
Basic statements:-
 Data definition language
 Select statement
 Create statement
 Alter statement
 Adding a column
 Renaming a column
 Drop statement
Select statement:-
Select * from<table_name>
Where<condition>;
Example
Select*from student
Where name= ali ;
Create statement:-
Create table <table_name>
( colume1 data_type,
colume2 data_type,…
colume n data_type);
aniket handore

11. 11
Example
Create table student
( std_id varchar(15),
Std_name varchar(20),
Std_address varchar(40));
Alter statement:-
Alter table <table_name>
Add(colume1 data_type,colume2 data_type,column
Data_type);
Example
Alter table student
Add (roll_no varchar(10),std_age varchar(3));
Drop statement:-
Drop table <table_name>;
Example
Drop table student;

12. 12
Basic statements:-
 Data manipulation language(DML)
 Insert statement
 Delete statement
Insert statement:-
Syntax:
Insert into <table_name> (colume1,colume2,..colume n)
Values(value1,value2,…value n);
Example:
Insert into student (std_id,name,address)
Values(10,ali,abc);
Delete statement:-
Syntax:
Delete from <table_name>
Where (condition);
Example:
Delete from student
Where std_id=10;

DBMS Security:-
 The unit of data used in specifying security in the database can be,
for example;
 the entire database
 a set of relations
 individual relation
 a set of tuples in a relation
 individual tuple
 a set of attributes of all tuples
 an attribute of an individual tuple.
Security:-
 Database Security involves protection against:
 unauthorized disclosures
 alteration
 destruction
Stop people without db access from having any access.
