DescriptionAn ultra-fast, open source Key-value store fully compatible with Redis API, modules, and protocolsQpenQM is a high-performance, self-tuning, multi-value DBMSIndustry 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.Distributed Analytical Database to replace Hadoop+MPP hybrid architectureVirtuoso is a multi-model hybrid-RDBMS that supports management of data represented as relational tables and/or property graphs
