I would like to understand how the real time DB works and how to use it.
Hello @tanasetaro, the real-time database has four main functions.
The get function
The save function
The AddListener function
And the RemoveListener function
To save someone’s data you will need to perform a sign-in function to get the users ID. Then you can perform a Save function using the ID from the sign-in as the key and store their data in an object form.
Have a look at this example I have made.
(Please note you will have to supply your own API key and database URL)
