Name

Description

High performance, persistent RDF store with additional support for Graph DBMS

Widely used open source RDBMS

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.

Cassandra and DynamoDB compatible wide column store

A distributed graph DBMS built for enterprise-level graph applications
