Database:-
overview
collection of logical related
data it can easily access
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
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)

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

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
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;
aniket handore

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;

13
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.
