DescriptionMulti-model database supporting relational and graph data models and built upon PostgreSQLWidely used open source RDBMS infoDeveloped as objectoriented DBMS (Postgres), gradually enhanced with 'standards' like SQLDistributed, high-performance timeseries databasePopular in-memory data platform used as a cache, message broker, and database that can be deployed on-premises, across clouds, and hybrid environments infoRedis focuses on performance so most of its design decisions prioritize high performance and very low latencies.Virtuoso is a multi-model hybrid-RDBMS that supports management of data represented as relational tables and/or property graphs
