ArangoDB

ArangoDB is a native multi-model database that supports documents, graphs, and key-value pairs in a single engine. It is designed to simplify data architecture by allowing developers to store and query different data models using a single, unified query language (AQL). This makes it an excellent choice for applications that require complex data relationships alongside flexible document storage.

ArangoDB's ability to perform graph traversals and document queries in the same transaction makes it a powerful tool for building modern, data-driven applications that would otherwise require multiple database systems.
