Name	AnzoGraph DB  Xexclude from comparison	RethinkDB  Xexclude from comparison	RRDtool  Xexclude from comparison
Description	Scalable graph database built for online analytics and data harmonization with MPP scaling, high-performance analytical algorithms and reasoning, and virtualization	DBMS for the Web with a mechanism to push updated query results to applications in realtime.	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	Graph DBMS RDF store	Document store	Time Series DBMS
Secondary database models		Spatial DBMS
