轻松跨设备进行协作
Realtime syncing makes it easy for your users to access their data from any device: web or mobile, and it helps your users collaborate with one another.
构建无服务器应用
Realtime Database ships with mobile and web SDKs so you can build apps without the need of servers. You can also execute backend code that responds to events triggered by your database using Cloud Functions for Firebase.
针对离线使用进行了优化
When your users go offline, the Realtime Database SDKs use local cache on the device to serve and store changes. When the device comes online, the local data is automatically synchronized.
基于用户的强健安全机制
The Realtime Database integrates with Firebase Authentication to provide simple and intuitive authentication for developers. You can use our declarative security model to allow access based on user identity or with pattern matching on your data.
