ConceptBase
ConceptBase (a.k.a. ConceptBase.cc) is a deductive and object-oriented database management system developed at University of Skövde. Earlier development was done at University of Passau (1987-1992), University of Aachen (1992-2003), and University of Tilburg (1997-2013). It is mainly used for conceptual modeling and metamodeling in the domain of software engineering and related domains. ConceptBase.cc is free and open-source software.
ConceptBase combines the following features:
- Object-oriented concepts such as classes and inheritance
- Deductive rules evaluated by a Datalog engine
- Active rules conforming to the event condition action (ECA) paradigm
- Recursive function definitions
- Metamodeling with arbitrarily many abstraction levels (metaclasses, meta metaclasses)
ConceptBase implements O-Telos, which is a variant of the knowledge representation Telos.
The graphical user interface consists of a workbench to add new classes & objects and a highly configurable graph editor. The graphical types of nodes and linked can be defined via deductive rules, i.e. they can be context-specific.
