DescriptionEmbeddable document-store database library with JSON representation of queries (in MongoDB style)An open source graph database built for real-time streaming and compatible with Neo4jA multi-model, scalable, distributed NoSQL database, designed to provide highly reliable, flexible, and available data management across a configurable set of storage nodesIndustry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database. infoThe data is stored in a circular buffer, thus the system storage footprint remains constant over time.In-Memory RDBMS compatible to Oracle
