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

Widely used open source RDBMS

TypeDB is a strongly-typed database with a rich and logical type system and TypeQL as its query language

Virtuoso is a multi-model hybrid-RDBMS that supports management of data represented as relational tables and/or property graphs

Primary database model

Key-value store

Relational DBMS

Key/Value like access via memcached API

Graph DBMS
