arcadedb
ArcadeDB Multi-Model Database, one DBMS that supports SQL, Cypher, Gremlin, HTTP/JSON, MongoDB and Redis. ArcadeDB is a conceptual fork of OrientDB, the first Multi-Model DBMS. ArcadeDB supports Vector Embeddings.
Internally, DatAasee is realized as a three tier software architecture, where each tier is encapsulated in its own container. The inner data-tier is a multi-model NoSQL database ArcadeDB. The middle logic-tier is an (HTTP-JSON-REST) API-server and semantic-layer around the database realized via Connect (aka Benthos). The outer presentation-layer uses Lowdefy as a prototype frontend which exclusively uses the API. This multi-container application is deployed and orchestrated via Compose.
