JavaScript DBMS library

Natively in-memory DBMS with options for persistency, high-availability and clustering

A native Graph DBMS to store and maintain very large RDF datasets.

Full-featured RDBMS with a small footprint, either embedded into a Java application or used as a database server.

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