Question

I do not really understand the database in app development

Answer 1

Suppose you made a small game. A user plays your game and makes a high score. Now, where will that high score be stored? That's why you need a database in app development.

Answer 2

It's a very useful to you to have SQL fundamentals. sure you'll use it in most of your phone programming or others.

you can store your data even in a text file on the mobile and retrieve it by users requests and let them modify it and re save it in that file
all by SQL Statement
- ( SELECT phoneNum, email FROM TableName WHERE ...)
- ( Insert Into TableName ....) to add more data to your file
- ( UPDATE TableName SET phoneNum='01200247', email='[e-mail]' WHERE ...)

Answer 3

I would definitely not use SQL in a mobile application if there is any monetary value in the app. Securely coding an app is another hell that you won't have to experience if you use a pre configured database like firebase. There are too many apps on the play store that let you unlock free things with SQL injections.

Answer 4

If your app need to use data from a database it is yes.

In Mobile app development Solutions like Couchbase’s
Couchbase Mobile , Microsoft’s Azure Mobile Services , Amazon’s Cognito , and Google’s Firebase offer the all-important sync that enables apps to work both online and offline. I personally use firebase for all my Android apps. Web based apps are just okay with SQL
