Once the project is set up, we can start taking a look at how our database is going to be structured.

Real-Time Database

Firebase allows mobile developers to store and sync data between users and devices in real time using a cloud-hosted, NoSQL database. Updated data syncs across connected devices in milliseconds and data remains available if your app goes offline, providing a great user experience regardless of network connectivity.

Three data models come into the picture when thinking about the basic data a one-to-one communication app should handle:

users: This will store avatars, names, and push notification tokens. There is no need to store authentication data here as it is handled through a different Firebase API (authentication API).

messages: We will save each message on each chat room separately for easy retrieval using the chat room ID as a key.

chats: All the information about the opened chats will be stored here.
