App backend, also known as app backend, is called differently, but it refers to the same thing.

I have been using the app backend for a long time. However, on the Internet, some netizens (from the traditional industry) who are preparing to start an app have asked this question. Here I will give a brief introduction to the two main functions of the app backend.

Note that the app backend is not clearly defined and has a wide range. Therefore, I will only extract the two main functions of the app backend for parsing. In order to be easy to understand, accuracy will be sacrificed to a certain extent. If you already know what the app backend uses, you don't have to read it any more.

Scenario 1:

User a prefers to use the QQ music app to listen to songs. His QQ music app saves the list of songs he prefers most.

If the song list is saved only on the mobile phone, and his mobile phone is stolen, even if he buys a new mobile phone, the song list will be lost?

To solve this problem, the QQ music app can place the song list on a machine in the distance. After user a buys a new mobile phone, just move the list of songs on the distant machine back to the QQ music app.


Scenario 2:

I believe many people have sent express parcels.


Suppose there are two people a and B. When a sends something to B, he will call the courier and send it to B.


When you view the logistics, you can see a description similar to this "arriving at xx transfer station ". Things will arrive at B's hand only after the transfer station.


The situation on the app is similar. Assume that user a on the app needs to send a message to user B. This message also needs to go through the backend Transfer Station of the app to reach user B.



Summary:

From the above scenarios 1 and 2, we can summarize the two important functions of the app backend:


1. Remote Data Storage

2. Message Transfer
