Name

Description

OLTP - DBMS for mainframes and Linux/Unix/Windows environments

used typically together with the Natural programming platform

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.

A distributed in-memory data processing engine, underpinned by a strongly-typed RAM store and a general distributed computation engine

Search-as-a-service for web and mobile app development

Widely used open source RDBMS

Primary database model

Multivalue DBMS

Object oriented DBMS

Graph DBMS
Key-value store

Search engine

Relational DBMS

Key/Value like access via memcached API

Secondary database models
