Name

Description

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

Widely used open source RDBMS

Scalable Time Series DBMS based on HBase

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

Key/Value like access via memcached API

Time Series DBMS

Secondary database models

Document store
Spatial DBMS
