Description

High performance, persistent RDF store with additional support for Graph DBMS

Analytic DBMS for real-time computations and queries

dBase was one of the first databases with a development environment on PC's. Its latest version dBase V is still sold as dBase classic, which needs a DOS Emulation. The up-to-date product is dBase plus.

A distributed, RESTful search and analytics engine forked from Elasticsearch and based on Apache Lucene
