BASIC INTRODUCTION TO DBMS

INTRODUCTION TO DBMS
Why DBMS:
Human needs have increased tremendously. Now people are
doing much more composite tasks than ever before. The society has become very
complex. a person has to work with huge amount of information every day. In
order to work with the enormous information, we must have a system where we
can store, manipulate and share the information all over the world. It is one of the
core reasons for introducing Database Management Systems (DBMS) as well as
Relational Database Management Systems (R-DBMS) now-a-days.
So, one thing is clear to us that we store and manipulate data / information into a
database, where the database contains various types of tables for storing various
types of data / information.
DATA:
Whatever we are inputting from the keyboard is known as Data. It can also
be called as RAW FACTS / FIGURES
 Data never provides any meaning for us
Information:
 Processed Data is known as Information
 Information always gives meaning for us
Database:
Collection of information belongs to a particular topic (an organization)
written in a predetermined manner stored at a particular place is called as
database.
DBMS (Data Base Management System):
It is software which is present inside the database, which can maintain and
manage the data within the database.
