DescriptionFull-featured RDBMS with a small footprint, either embedded into a Java application or used as a database server.A distributed, linear scalable, high perfomant Graph DBMSWidely used in-process key-value storeIndustry 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.A general purpose database with bitemporal SQL and Datalog and graph queries
