INTRODUCTION
A database management system 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 (DBMSs)
are categorized according to their data structures or types.
Classification of database management system is based
on various parameters such as the kind of data model used
to construct the DBMS, the number of users that will be
using the database system, the way in which the database is
distributed.

1. Based on Data Model
The data model defines the physical and logical structure of a
database which involves the data types, Depending upon how the
data is structured, data models are further classified into:
a. Relational Data Model :-
In the relational data model, we use tables to represent data and
the relationship among that data. Each of the tables in the relational
data model has a unique name. A table has multiple columns where
each column name is unique. A table holds records which has value
for each column of the table.

b. Entity-Relationship Model:-
The Entity-Relationship model (E-R data model) represents data
using objects and the relationship among these objects. These
objects are referred to as entities that represent the real ‘thing’ or
‘object’ in the real world.
c. Object-Based Data Model:-
Nowadays, object-oriented programming such as Java, C++, etc. is
widely used to develop most of the software. This motivated the
development of an object-based data model. The object-based data
model is an extension of the E-R model which also include notion for
encapsulation, methods.
d. Semi structured Data Model:-
In the semi structured data model, the data items or objects of the
same kind might have a different set of attributes. The Extensible
Markup Language represents the semi structured data.

2. Based on Number of Users
The database management system can also be classified on the basis
of its user. So, a DBMS can either be used by a single user or it can be
used by multiple users.
a. Single user system:-
The database system that can be used by a single user at a time is referred
to as a single-user system. It is mostly used with the personal computer
on which the data resides accessible to a single person. The user
may design, maintain and write the database programs.
b. Multiple user system:-
the database system that can be used by multiple users at a time is
referred to as a multiple user system. It supports multiple users
Data can be both integrated and shared, a database should be
same information is not need be recorded in two places.

3. Based on Database Distribution:-
Depending on the distribution of the database over numerous
sites we can classify the database as:
a. Centralized DBMS:-
In the centralized DBMS, the entire database is stored in a
single computer site. Though the centralized database support
multiple users still the DBMS software and the data both are
stores on a single computer site.
b. Distributed DBMS:-
In the distributed DBMS (DDBMS) the database and the DBMS
software are distributed over many computer sites. These
computer sites are connected via a computer network. The
DDBMS is further classified as homogeneous DDBMS and
heterogeneous DDBMS.
•Homogeneous DDBMS: The homogeneous DDBMS has the
same DBMS software at all the distributed sites.

.Heterogeneous DDBMS: The heterogeneous DDBMS has
different DBMS software for different sites.
4. Based on Cost of Database:-
Low cost DBMS – The cost of these systems vary from $100
to $3000.
Medium cost DBMS – Cost varies from $10000 to $100000.
High cost DBMS – Cost pf these systems are usually more
than $100000.
5. Based on Usage:-
Online transaction processing(OLTP) DBMS – They manage
the operational data. Database server must be able to process
lots of simple transactions per unit of time. Transactions are
initiated in real time, in simultaneous by lots of user and
applications hence it must have high volume of short, simple
queries.
Online analytical processing(OLAP) DBMS – They use the
operational data for tactical and strategical decision making.
They have limited users deal with huge amount of data,

Big data and analytics DBMS – To cope with big data new
database technologies have been introduced. One such is
NoSQL (not only SQL) which abandons the well known
relational database scheme.
6. Based on Flow Control:-
Based upon the flow of control from application to DBMS the
database management system is broadly classified into two types
active database management system and passive database
management system.
With the passive database management system, the user needs
to specify the query to the current state of the database system to
retrieve the desired information.
The active database management system on other hand are
referred to as data-driven systems or event-driven systems where
the control flow between the application and DBMS is based on the
occurrence of an event.
