Which application is best suited for a graph database?

A log aggregation system for storing application logs

A financial ledger requiring ACID transactions

A recommendation engine that analyzes user-item interactions

A product catalog with varying attributes per product

For which application requirement is a relational database typically the best choice?

Ingesting high-velocity sensor data with timestamps for real-time monitoring

Storing unstructured data with varying fields per record

Analyzing large volumes of data with aggregate queries over many columns

Storing and querying complex relationships between entities with ACID transactions

A DevOps team is building a monitoring system that ingests millions of metrics per second. They need to store raw metrics for 30 days and also provide dashboards that aggregate metrics over time. They are considering using a time series database for raw data and a columnar database for long-term analytics. What is the primary trade-off they are addressing?

Balancing consistency with availability

Balancing write throughput with query performance

Balancing real-time ingestion with analytical query performance

Balancing storage cost with data retention

Which application is best suited for a time series database?

Analyzing social network connections

Managing customer orders with complex relationships

Storing user profiles with varying attributes

Monitoring infrastructure metrics such as CPU usage and network latency
