Show answer & explanationAnswer & explanation
Correct answer: D. Google Cloud Firestore
Google Cloud Firestore is a flexible, scalable NoSQL document database designed for mobile, web, and server development. It offers real-time synchronization, offline support, and is fully managed, perfectly suiting the requirements.
Why the other options are wrong
- A. Cloud SQL is a relational database, not NoSQL, and doesn't offer real-time synchronization or offline capabilities directly.
- B. Cloud Spanner is a globally distributed relational database, not NoSQL, and is generally for different use cases than a mobile backend with real-time sync.
- C. Bigtable is a NoSQL wide-column database for analytical and operational workloads with very high throughput, but lacks the real-time sync and offline capabilities of Firestore for mobile apps.
