Realtime Database
Realtime Database is a cloud-hosted NoSQL database that stores and syncs data in real-time across connected clients. It uses a JSON-like data structure and provides low-latency updates, making it ideal for applications requiring live data synchronization, such as chat apps, collaborative tools, and live dashboards. Data is synchronized automatically to every connected device, enabling seamless user experiences without manual refresh.
Developers should use Realtime Database when building applications that require instant data updates across multiple users or devices, such as real-time messaging, multiplayer games, or live tracking systems. It eliminates the need for polling or manual sync logic, reducing development complexity and improving performance. However, it's best suited for smaller-scale projects or prototyping due to scalability limitations compared to alternatives like Firestore.
