How does MongoDB Atlas compare to Google Firestore for web and mobile applications?

Google Firestore is optimized for real-time sync and offline-first mobile/web applications with native SDKs for iOS, Android, and Flutter. MongoDB Atlas is better for complex queries, aggregations, and backend APIs. Atlas Device Sync brings similar real-time capabilities to Atlas for mobile use cases.

What are the key schema design principles for document databases?

Document database design favors embedding related data within documents (denormalization) when accessed together, using references for many-to-many relationships or independently accessed entities. Avoid large unbounded arrays, design for query patterns rather than normalized form, and consider document size limits (MongoDB: 16MB per document).

How do enterprises handle transactions in managed document databases?

MongoDB Atlas supports ACID multi-document transactions since v4.0, enabling complex operations across multiple documents. Firestore supports atomic transactions within a single document or batch writes. For financial or inventory applications requiring strong consistency, PostgreSQL JSONB or AWS Aurora may offer better transaction guarantees than pure document stores.
