Name

Description

A RDF storage and query DBMS, shipped as an optional-use component of the Apache Jena framework

Widely used open source RDBMS

NuoDB is a webscale distributed database that supports SQL and ACID transactions

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.

Primary database model

RDF store

Relational DBMS
