Realm Database Mobile څه شی دی

Realm is an embedded mobile database for iOS, Android, and React Native that prioritizes offline-first functionality and cloud sync. Unlike REST APIs that require network connectivity, Realm stores data locally on the device and synchronizes to MongoDB Cloud asynchronously. Apps read and write to the local database instantly, giving users a fast, responsive experience whether online or offline. Realm is object-oriented: you define data models in code, and Realm handles persistence, indexing, and ACID transactions automatically. When you enable Realm Sync, changes sync bi-directionally with MongoDB Cloud.

❓ ډېرې پوښتل شوې پوښتنې

Why Realm over SQLite?
Realm is object-oriented (no ORM boilerplate), faster queries, and has built-in cloud sync. SQLite requires manual sync logic. Realm is better for modern mobile.
Does Realm work offline?
Yes, that's its strength. All data is stored locally. When network returns, Realm syncs with MongoDB Cloud automatically (if configured).
What happens if the device is offline for a week?
Data stays on device and syncs when connected. Realm handles merge conflicts via custom resolution functions or default strategies (last-write-wins).
Can multiple users collaborate?
Yes, via Realm Sync. Users sync to the same MongoDB collection. Realm detects changes and merges them (with conflict resolution).
Is Realm free?
Realm database is open-source and free. MongoDB Cloud Sync has a free tier (up to 100MB data). Larger apps pay per-GB.
