Description

In-memory JavaScript DBMS

TimeSeries DBMS for AIoT and BigData

Widely used open source RDBMS

Open Source Operational and Transactional Enterprise NoSQL Document Database

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

Document store

Time Series DBMS

Relational DBMS

Key/Value like access via memcached API
