In this video series we are going to learn, how to use the Cloud Firestore database to store and retrieve data in an Android app.
Firestore is a cloud-hosted database that makes it easy to synchronize data in realtime between multiple connected client apps and across different platforms, without us having to manage our own servers.
Firestore is a schemaless NoSQL database and stores it’s data in documents which each contain a set of key-value pairs (fields). These fields can be simple datatypes like strings, integers and booleans, but also geographical points, raw binary values, timestamps, arrays, nested objects (maps) etc.
Documents are organized into collections and can contain subcollections.
