This document provides an introduction to database management systems (DBMS) and relational database management systems (RDBMS). It defines a database as a collection of related data organized for easy access, management, and updating. A DBMS is software that allows users to create, define, and manipulate databases. It provides protection and security. RDBMS introduced the relational model, using relationships between tables via primary keys, foreign keys, and indexes. This made data fetching and storage faster compared to earlier navigational models. RDBMS is widely used by enterprises for complex, large datasets.

Introduction to Database
DBMS and RDBMS

2.  A Database is a collection of related
data organised in a way that data can
be easily accessed, managed and
updated. Any piece of information can
be a data, for example name of your
school. Database is actually a place
where related piece of information is
stored and various operations can be
performed on it.

3.  DBMS is the abbreviated form of DataBase
Management System.
 Database management system is a computer software
component introduced during 1960’s
A DBMS is a software that allows creation, definition
and manipulation of database. Dbms is actually a tool
used to perform any kind of operation on data in
database. Dbms also provides protection and security
to database. It maintains data consistency in case of
multiple users. Here are some examples of popular
dbms, MySql, Oracle, Sybase, Microsoft Access and
IBM DB2 etc

4.  The database system can be divided into four
components.
 Users : Users may be of various type such as DB
administrator, System developer and End users.
 Database application : Database application may be
Personal, Departmental, Enterprise and Internal
 DBMS : Software that allow users to define, create and
manages database access, Ex: MySql, Oracle etc.
 Database : Collection of logical data.

5.  Dictionary Management
 Data Storage Management
 Data Transformation and Presentation
 Security Management
 Multi user Access Control
 Backup and Recovery Management

6.  RDBMS is the abbreviated form of Relational
DataBase Management System.
 Relational database management system was
introduced in 1970’s by E.F CODD
 RDBMS avoided the navigation model as in old DBMS
and introduced Relational model. The relational
model has relationship between tables using primary
keys, foreign keys and indexes. Thus the fetching and
storing of data become faster than the old
Navigational model. So RDBMS is widely used by
the enterprises and developers for storing complex and
large amount of data

8. 1 Introduced in 1960S Introduced in 1970s.
2
During introduction it
followed the navigational
modes (Navigational DBMS)
for data storage and fetching.
This model uses
relationship between
tables using primary keys,
foreign keys and indexes.
3
Data fetching is slower for
complex and large amount of
data.
Comparatively faster
because of its relational
model.
4
Used for applications using
small amount of data.
Used for huge applications
using complex and large
amount of data.
5
Example systems are
dBase, Microsoft Acces,
LibreOffice Base, FoxPro.
Example systems are SQL
Server, Oracle , MySQL,
Maria DB, SQLite.
