This document discusses database management systems and how they are used. It provides definitions of DBMS and describes the main types: hierarchical, network, relational, and object-oriented. Amazon is used as an example of a company that relies heavily on DBMS to store customer, order, and product data. A DBMS allows Amazon to track sales, analyze growth, and securely access customer accounts. Benefits of DBMS include fast data access, data integration, storage efficiency, and data security.

5. Database Management Systems
• It is a collection of programs the enables you
to store, modifies, and extracts information from
a database.
• Database management system can house
wealth of information in one place; it had been
designed to maintain the integrity and security
of stored data, and recovering information if the
system fails.

7. Database Management System Types


Hierarchal DBMs:
is when the relationships among data in the
database are established in a way that one data item
is present as the subordinate of another one. No
backward movement is possible in this type of
DBMS

8. Database Management System Types


Network DBMs:
the relationship appear in the form of network, and it
is extremely complicated Ex.
Pascal, C++, FORTRAN.

9. Database Management System Types


Relational DBMs:
If the database relationships are treated in the form
of a table, It's a set of records and a field contains
one –to- many relationships. Examples of RDBMS
are Oracle, Microsoft SQL and Microsoft Access..

10. Database Management System Types


Object-oriented DBMs:
This type can handle many new data types, including
graphics, photographs, audio and video. An objectoriented database can be used to store data from
variety of media sources unlike the Hierarchical and
network databases

12. How Amazon uses Database Management System
Amazon has the world's largest databases with
thousands of entries concerning its
products, marketplace sellers, millions of orders and
customer information. Such as, payments, visitors'
browsing and product information.


13. How DBMSs Help the growth of Amazon

Retail industry;
storing data related to their sales in order to

18. Database Management Systems’ Benefits

1) Fast response to information requests;

the data is always integrated into a single database, and complex
requests can be handled much more rapidly. For businesses, faster
response means better customer services.

2) Multiple accesses;

DBMs allows data to be accessed in a variety of ways by using
several programming languages.

3) Less storage;

it can eliminate the storage of redundant data.

4) Decrease duplication of data;

the presence of integrated data in multiple locations reduces the
duplication of data.

19. Database Management Systems’ Benefits

5) Understandable data:

all data is stored in format that is extremely easy to make sure
users don't have any difficulties in the same service.

6) Extreme data validity;

DBMS are valid, accurate and up-to-date.

7) intensive data security;

organization can ensure that only appropriate users are in
control, in this way it prevent any confidential data from
getting into the wrong hands.
