DescriptionA RDF storage and query DBMS, shipped as an optional-use component of the Apache Jena frameworkAll data is stored inside objects which are linked by so-called link attributes. Objects consist of classes which can be extended and de-extended at runtime. Graphs can be defined with a struct.Embeddable relational database for web apps written in pure JavaScriptBased on PostgreSQL enhanced with MPP and write-scale-out cluster featuresScalable Graph Database platform making enterprise data available by exploiting inferred entities and relationships
