Firebase realtime database delete child

A real-time database is a database system which uses real-time processing to handle workloads whose state is constantly changing . This differs from traditional databases containing persistent data, mostly unaffected by time. For example, a stock market changes very rapidly and is dynamic.

Firebase works with two different databases. The Real-Time Database is the original Firebase database product, and Cloud Firestore is a new and improved version of the Real-Time Database . Firebase offers file storage security for users and enables them to utilize Google Cloud Storage.

You can use both Firebase Realtime Database and Cloud Firestore in your app , and leverage each database solution’s benefits to fit your needs. For example, you might want to leverage Realtime Database’s support for presence, as outlined in Build Presence in Cloud Firestore.
