UNIT 1
Introduction to DBMS
, Database
DBMS stands for Database Management System.
We can break it like this DBMS = Database +
Management System.
Database is a collection of data and Management Sys
is a set of programs to store and retrieve those data.
Based on this we can define DBMS like this: DBMS is
collection of inter-related data and set of programs to
store & access those data in an easy and effective
manner.
, What is the need of DBMS?
Database systems are basically developed for large amount of data
When dealing with huge amount of data, there are two things that
require optimization:
Storage of data
and retrieval of data.
, Storage
According to the principles of database systems, the data is stored
such a way that it acquires lot less space as the redundant data
(duplicate data) has been removed before storage.
