ArcadeDB

An open-source multi-model database engine that stores graphs, documents, key-value pairs, vectors, full-text search, and time-series in one system to avoid using multiple specialized databases. It is for software developers, data and IT teams in businesses that build applications requiring graph traversals, analytics, and mixed data models. It is positioned as a single native engine that removes translation layers and supports SQL, Cypher, Gremlin, GraphQL, and MongoDB query protocols with ACID transactions.
