History

TypeDB originally started as the Grakn Project in 2016 at the University of Cambridge Computer Lab. It then spun out as a commercial product in 2017. The system was renamed to TypeDB in 2021.

Data Model[05]

Grakn supports the enhanced entity-relationship model, implemented with a hyper-graph. Users can model type hierarchies, hyper-entities, hyper-relationships, and rules.

Query Interface[06]

Graql is the query language for the Grakn knowledge graph. It is declarative language that is specific to Grakn. Graql enables an application to describe what information it would like to retrieve, rather than how should it be obtained.

Graql serves as both the Data Manipulation Language (DML) as well as the Data Definition Language (DDL) Graql is a language that provides you with a complete set of tools to perform all data-oriented tasks. This includes defining the schema, retrieving information as well as creating and manipulating data.
