Description

Fast, reliable graph database built for the cloud

Analytic DBMS for real-time computations and queries

All 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 fast key-value storage library that provides an ordered mapping from string keys to string values

Primary database model

Graph DBMS
RDF store

Relational DBMS

a hierachical model (tree) can be imposed
