Hello im willing to code a webstore for my sister's business(and of course learning something in the way) im familiar with C++, Java and Html, and a liiitle with sql databases, Im wondering which languages i should be looking to learn in order to make a:
-Server/webstore -An app (android and ios) who feeds info from the server
Designing the webstore/app its not my problem, but feeding them with user account/items/etc is where im lost.
I hope you can help me thanks in advance!
For a no frills backend, I suggest taking a look into what Parse and Firebase offers. You can then just use REST-ful calls to them. Firebase also support user accounts (even anonymous accounts) + authentications right out of the box.
