Do I Understand Mongodb Realm Correctly?
There Are Three Components: Realm Database: Local Storage & Persistence Realm Sync: Sync Realm Databases Between Clients and the Mongo Db Atlas Mongo Db Atlas...
There are three components:
- Realm Database: Local Storage & Persistence
- Realm Sync: Sync Realm Databases between clients and the Mongo DB Atlas
- Mongo DB Atlas: A Cloud Database.
You can use each separately or together. So you can
- Just store data locally with Realm Database and not sync it
- Just store data on Mongo DB Atlas without using realm sync, using standard queries to access the data.
- Use realm sync to create a synced realm that partitions your mongo db atlas database into a local realm and syncs data between the database and all clients who use it.
Is this all correct? (Thank you)

below are some notes for your questions. I'm just getting setup with MongoDB and Realm, myself.
A - Tools
Realm Database: Local Storage & Persistence
Correct - Client (on-device / local) storage
Realm Sync: Sync Realm Databases between clients and the Mongo DB Atlas
Somewhat confusingly, there's 2 different implementations of Realm Sync:
- Realm Sync - Syncs between clients with Realm (no MongoDB implementation necessary). This uses Realm-run database which costs $30/month
- MongoDB Realm with Sync - Syncs between Realm clients and MongoDB + Atlas backend which has a 'free forever' sandbox tier.
Mongo DB Atlas: A Cloud Database.
Correct - A database cluster + UI that is used in most tutorials to setup data models & database configuration.
