The document discusses a database management system (DBMS) prepared by three students and guided by a professor. It provides an overview of DBMS, including a brief history tracing it back to the 1960s, purposes such as storing and retrieving data for applications, data modeling, architecture/layers, advantages/disadvantages, languages used, and components. The key functions of a DBMS are to store, retrieve, and query data, acting as a link between databases and end users or application programs.

3. WHAT IS DBMS?
A database management system (or DBMS) is essentially nothing more than a computerized
data-keeping system. Users of the system are given facilities to perform several kinds of
operations on such a system for either manipulation of the data in the database or the
management of the database structure itself.
Database Management Systems (DBMS) are software system used to store,retrieve,and
queries on data.
The database management system is the link between the
databases and the end users or application programs.

4. BRIEF HISTORY ABOUT DBMS?
Edgar Frank "Ted" Codd (19 August 1923 – 18 April 2003) was an English computer
scientist who, while working for IBM, invented the relational model for database
management, the theoretical basis for relational databases and relational database
management systems.
It was developed in early 1960's. In the late 1960's, IBM (International Business
Machines Corporation) developed the Integrated Management Systems which is the
standard database system used till date in many places. It was developed based on
the hierarchical database model.
In 1960, Charles W. Bachman designed the integrated database system, the “first”
DBMS. IBM, not wanting to be left out, created a database system of its own, known
as IMS. Both database systems are described as the forerunners of navigational
databases.

5.  HISTORY OF DBMS?

6. WHY WE USE DBMS?
 Application and Uses of Database Management System (DBMS):
 Due to the evolution of Database management systemAs, companies are getting more from
their work because they can keep records of everything.
Also, it makes them faster to search information and records about any people or product that
effective in work. So here we are sharing some of the applications and uses of the database
(DBMS).
 1.Railway Reservation System
The database is required to keep record of
 ticket booking, train departure, and arrival status.
 Also if trains get late then people get to know it
 through database updates.

7. 2.Library Management System
There are thousands of books in the library so it is very difficult to keep record of all the
books in a copy or register. So DBMS is used to maintain all the information related to
book issuing dates, name of the book, author, and availability of the book.
3.Banking Management system
We make thousands of transactions through banks daily and we can do this without
going to the bank. So how banking has become so easy that by sitting at home we can
send or get money through banks. That is all possible just because of DBMS that
manages all the bank transactions.

8. WHAT ARE THE PURPOSE OF DBMS?
• The purpose of DBMS is to transform the following:-
1. Data into information.
2. Information into knowledge.
3. Knowledge to the action.
• The diagram given below explains the process as to how the transformation of data to
information to knowledge to action happens respectively in the DBMS:-
