ArangoDB vs Couchbase

ArangoDB is an open-source multi-model database that combines document, graph, and key-value data models in a single engine. It uses AQL (ArangoDB Query Language) for querying across all data models and supports distributed deployments.

Couchbase is a distributed NoSQL database providing high performance, high availability, and flexible data models for modern applications. It combines document-oriented flexibility with traditional database reliability.
