NameApache Cassandra  Xexclude from comparisonMicrosoft Access  Xexclude from comparisonRRDtool  Xexclude from comparisonVelocityDB  Xexclude from comparison
DescriptionWide-column store based on ideas of BigTable and DynamoDB infoOptimized for write accessMicrosoft Access combines a backend RDBMS (JET / ACE Engine) with a GUI frontend for data manipulation and queries. infoThe Access frontend is often used for accessing other datasources (DBMS, Excel, etc.)Industry 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 .NET Object Database that can be embedded/distributed and extended to a graph data model (VelocityGraph)
