For our comparison, we've picked the 10 most commonly used database management systems: MySQL, MariaDB, Oracle, PostgreSQL, MSSQL, MongoDB, Redis, Cassandra, Elasticsearch, and Firebase. Concentrating on their business-related benefits and the challenges, we'll also outline the best use cases for each. Saving user related data e.g. profile information, with Cloud Firestore is easy. Once you have an authenticated user's unique identifier you can start to save documents in your Firestore with the UID as an identifier. Each time the user logs in you just look up the document in your Firestore to retrieve the related information about this user. Firebaseuser instance is kept for every provider linked to the user, and when a user is registered or signs in, that user becomes the current user of the Auth instance. The instance persists the user's state so that refreshing the page or restarting the application doesn't lose the user's information.
