DescriptionApplication development environment with integrated database management systemHarperDB takes the "stack" out of "tech stack" by combining an ultra-fast document-style data store, in-memory cache, real-time message broker, and your application components into a single distributed technology.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.Cassandra and DynamoDB compatible wide column storeTransactional SQL-on-Hadoop DBMS
