What is Firebase Realtime Database?
The Firebase Realtime Database is a NoSQL database that allows us to store and sync data in real-time between our users. It's a large JSON object that developers can manage in real-time. The Firebase database gives the application with the current value of the data as well as updates to that data via a single API. Our users can access their data from any device, web or mobile, thanks to real-time syncing. Our users can collaborate with one another thanks to the real-time database. It includes mobile and web SDKs, allowing us to build our app without the use of servers. When our users go offline, the Real-time Database SDKs use the device's local cache to serve and store changes. When the device connects to the internet, the local data is automatically synchronized.
- The most important features of a real-time database
A real-time database can provide both offline and online services. These capabilities include client-side accessibility, scaling across multiple databases, and many more.
- Data synchronization is used in real-time databases.
Instead of using HTTP requests, the Firebase Real-time database employs data synchronization. The updates are delivered to any connected device in milliseconds. It is not concerned with network code and instead provides collaborative and immersive experiences.
- Even when it is offline, it is responsive.
Because the Firebase Database SDK saves our data to disk, Firebase apps remain responsive even when they are not connected to the internet. Once connectivity is restored, the client device receives the missed chances.
- Client devices can access it.
The Firebase Real-time database does not require the use of an application server. We can get to it using a mobile device or a web browser. Data validation and safety are given by the Firebase Real-time Database Security Rules, which are expression-based rules that are executed when data is read or written.
- Using multiple databases to scale
We can support our app's data needs with the Firebase Real-time Database on the Blaze Pricing Plan by splitting our data across multiple database instances in a single Firebase project. Streamline authentication on our project with Firebase authentication and authenticate users in our database instances. Controls data access in each database using custom Firebase real-time database rules for each database instance.
Aside from Firebase's real-time database, several alternatives are used.
- Cloud Firestore
Cloud Firestore is a scalable and flexible database from Firebase and Google Cloud Platform that is used for server development, mobile, and web.
- Firebase Remote Configuration
It saves key-value pairs specified by the developer in order to change the behavior and appearance of our app without requiring users to download an update.
- Hosting on Firebase
- Storage in the Cloud
It is used to store images, videos, audio, and other forms of user-generated content.
