ArangoDB
ArangoDB is a native multi-model database that supports key-value, document, and graph data models in a single database engine and query language (AQL). It allows developers to combine different data models in queries and applications without the need for complex integrations. The database is designed for high performance, scalability, and flexibility, making it suitable for modern applications with diverse data requirements.
Developers should learn and use ArangoDB when building applications that require handling multiple data types (e.g., JSON documents, graph relationships, and key-value pairs) in a unified way, such as in social networks, recommendation engines, or real-time analytics. It is particularly valuable for scenarios where reducing data silos and simplifying architecture with a single database solution is a priority, offering benefits like reduced operational overhead and improved query flexibility.
