TypeDB is a polymorphic database with a conceptual data model, a strong subtyping system, a symbolic reasoning engine, and an elegant type-theoretic language TypeQL.
TypeDB was crafted to solve the inability of current database paradigms to natively express these polymorphic features. TypeDB is composed of two parts: TypeDB the storage, and TypeQL the language.
This is free and open source software.
Key Features
- Entity-Relationship Model – model domains using the entity-relationship (ER) model. It is composed of entity types, relation types, and attribute types, with the introduction of role types.
- Type Hierarchies – model type inheritance into their domain model. Following logical and object-oriented principles, TypeDB allows data types to inherit the behaviors and properties of their super types.
- N-ary Relations – represent an arbitrary number of things as one relation.
- Nested Relations
- Logical Data Validation – performs validation of inserted entities and relations by evaluating the polymorphic types of the things involved.
- Logical Query Validation – queries executed on TypeDB undergo a type resolution process.
- Allows users to define rules within their schemas. This feature enhances the expressiveness of the model by enabling the system to derive new conclusions when specific logical conditions within a dataset are satisfied.
