A Collection of logical
related data it can easily
access.
Data store in
Tables, Rows
And Column
Data
Base

6. 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.
Database management

7. 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.

8. Introduction of Airport
Managements System
 We used DBMS in airport 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.

9. 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.

10. 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.

11. Implement of DBMS
 Analyze user environment.
 Develop logical model.
 Choose DBMS.
 Map logical model DBMS.
 Develop physical Design.
 Evaluate Physical Model.

12. Requirements of AMS
 Database management system required a operating system
that have 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.

13. Entities & Attribute
 ENTITY : Airpot
ATTRIBUTES (Airpot_id, Airpot_name, city)
 ENTITY : Employee
ATTRIBUTES (emp _id, emp _ name, emp_age, Airport_name,
salary, Job, emp_Address)
 ENTITY : Passengers
ATTRIBUTES (p_id, p_name, p_age, p_address, country_name)
 ENTITY : Airline Companies
ATTRIBUTES (c_id, c_name, city, country)
 ENTITY : Ticket
ATTRIBUTES (order_no, flight_name, seat_class, price, passenger_name)
 ENTITY : Flight time
ATTRIBUTES (Flight_no, Airport_name , Arrivals_hours , Aiport _arrival,
Departure_Hours)

16. Description
 Airport has employees
 Employees serve passengers
 Passengers purchases tickets
 Flight carries passengers
 Ticket belongs to flight

17. Models of DBMS
Data Model is a collection of concept used to describe
the structure of a data.
It contains data types, relationships, and constraints.
 Hierarchical model
 Network model
 Relational model

18. Relational Model
 Conceptually simple
 Computers lacked power to implement the relational model
 We are using the RDBMS in this data model
 RDBMS has its ability to hide the complexities of the
relational model from the user.
 It contains tables.

19. 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
 Create table
 Insert into
 Delete table

20. Basic statements
 Data definition language
 Select statement
 Create statement
 Alter statement
Adding a column
Renaming a column
 Drop statement

21. Select statement
Select*
From<Table Name>
Where<Condition>
Example
Select*
From student
where name = Ali;

22. Create statement
Create table <table name>
(Column 1 data type,
Column 2 data type…
Column n data type)
Example:
Create table <Student>
{std_id varchar (15)
Std _name varchar(20)
Std_address varchar (40)};

23. Alter statement
Alter table <table name>
ADD(Column 1 data type,Column 2 data type…, Column n data
type);
Alter table student
Add(Roll_no varchar(10),std_age varchar(3));

24. Drop Statement
 Syntax:
 Drop Table <table name>
 Example:
 Drop Table Student;

25. Basic statements
 Data manipulation language(DML)
 Insert statement
 Delete statement

26. Insert statement
Syntax:
insert into <table name> (column 1, coulmn 2…,
column n)
Values (value 1, value2,… value n);
Example:
insert into student ( std _id, std_name, std-address)
Values (10, Ali, ABC)

27. Delete statement
Syntax:
delete from <table name>
where (condition)
Example:
delete from student
where std_id=10;

28. 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.

29. Security
 Database Security involves protection against:
 unauthorized disclosures
 alteration
 destruction
 Stop people without db access from having any access.
