Description

JavaScript DBMS library

Hosted, scalable database service by Amazon with the data stored in Amazons cloud

Spatial extension of H2

Database as a Service offering with high compatibility to Microsoft SQL Server

Industry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database.

The data is stored in a circular buffer, thus the system storage footprint remains constant over time.
