Firestore is Google’s serverless document database offering.
What does serverless mean?
Serverless means that we don’t have to worry about managing the servers on which the database runs. All the management is done automatically by Google. The database will scale up or down depending on the demand.
What’s a document database?
A document database is a non-relational database that stores data in a semi-structured format. A common format used by many document databases is JSON.
In a relational database, we usually create tables with a defined structure (columns and types). In a document database, it’s not necessary to specify the different columns.
