Name

Description

Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

An open source immutable (append-only) database with cryptographic verification which makes it tamper-resistant and fully auditable.

Microsoft Access combines a backend RDBMS (JET / ACE Engine) with a GUI frontend for data manipulation and queries.

The Access frontend is often used for accessing other datasources (DBMS, Excel, etc.)

A .NET Object Database that can be embedded/distributed and extended to a graph data model (VelocityGraph)

Primary database model

Wide column store

Key-value store

Relational DBMS

Graph DBMS
Object oriented DBMS

Secondary database models
