let’s learn about the Need for DBMS
What is the need for DBMS?
Database systems are basically developed for a large amount of data. When dealing with a huge amount of data, there are two things that require optimization:-
Storage of data: According to the principles of database systems, the data is stored in such a way that it acquires lot less space as the redundant data (duplicate data) has been removed before storage. Let’s take a layman example to understand this: In a banking system, suppose a customer is having two accounts, one is a saving account and another is a salary account. Let’s say the bank stores saving account data at one place (these places are called tables we will learn them later) and salary account data at another place, in that case, if the customer information such as customer name, address, etc. are stored at both places then this is just a wastage of storage (redundancy/ duplication of data), to organize the data in a better way the information should be stored at one place and both the accounts should be linked to that information somehow. The same thing we achieve in DBMS.
Fast Retrieval of data: Data retrieval means obtaining data from a database management system. Along with storing the data in an optimized and systematic manner, it is also important that we retrieve the data quickly when needed. Database systems ensure that the data is retrieved as quickly as possible. The retrieved data may be stored in a file, printed, or viewed on the screen.
