Firebase Realtime Database allows real-time data synchronization across all connected devices. Changes made to the database are reflected instantly on every client, enabling dynamic user experiences.

Its offline capabilities ensure that data is cached locally on the client device, allowing users to access and modify data even without an internet connection. Changes are synchronized automatically when the connection is restored.
