Name

Description

JavaScript DBMS library

A distributed, linear scalable, high perfomant Graph DBMS

Widely used 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.

Enterprise Knowledge Graph platform and graph DBMS with high availability, high performance reasoning, and virtualization

Primary database model

Document store
Relational DBMS

Secondary database models

Document store
Graph DBMS

with Oracle Spatial and Graph
RDF store

Spatial DBMS

with Oracle Spatial and Graph
Vector DBMS

since Oracle 23
