What is the use of database?

Question

why we need database to save our new software data.but when we create a folder in my computer it dosent need database and automatically saves

Answer 1

again.. when you install software it does get saved into a database.. called the registry. databases are everywhere

Answer 2

Not all applications run on your computer, think about your own Facebook, or YouTube accounts, (or anything you might use) and you'll notice they need to be stored some way. Databases are fundamental when you come to develop complex web applications, or you're storing data that is too important to be stored on the user's computer.
Your own computer contains a database by the way, I talked about online databases because I imagined that's what you were asking about, considering the nature of this application (and the fact it has sql courses).

You're gonna need to make more accurate questions to get proper answers. Why are you asking, what do you mean by "need databases", what do you mean by "saves automatically", etc... Your question is very unclear.

Answer 6

The main use of database is to store data and use them whenever required. We use database to store software data because it is simple to use and manage. In a database data is more secure.

Answer 7

Databases provide an efficient way to store, retrieve and analyze data. While system files can function similarly to databases, they are far less efficient. Databases are especially important for business and research

Answer 9

databases are great for business systems - you can use one database to safely store all the data for all the custom made software that the business has, so data can be used between different departments without having to copy over files everywhere and without having issues around one department updating a file that another department will use

Answer 10

there are ways to do it without a database, but really it's neither efficient, nor effective enough for certain things. what you might use instead is a write/read methods and create a save file that way. if you're developing for web, databases are the way to go

Answer 16

Database is where we save server side programming codes like php etc and we can retrieve information from database anytime. There are many types of databases like SQL, MySQL, etc. MySQL is most popular database these days because it is free to use.

Answer 17

I think if you want to take the development career seriously you should start searching for answers by yourself. I mean, it's a good thing to ask in forums, but first you've got to try answering your own questions . E.g. you should have first checked wikipedia for this (https://en.wikipedia.org/wiki/Database). Then, if you don't understand something: google it.
This is trivial information and you need to learn to gather this kind of information for yourself.
