A recommendation engine needs to suggest products based on user behavior and product similarities. The data includes users, products, and interactions (views, purchases). The team wants to run queries like 'find products frequently bought together' and 'recommend products based on similar users'. They are considering a graph database. What is the primary advantage of using a graph database over a relational database for this use case?

Graph databases are more efficient for multi-hop relationship queries

Graph databases provide better ACID transaction guarantees

Graph databases are easier to scale horizontally

Graph databases require less storage for the same data

Which use case is most appropriate for a columnar database?

An online transaction processing (OLTP) system with frequent updates

A data warehouse running complex analytical queries on large datasets

A real-time sensor data ingestion system

A social network analyzing friend connections
