Explanation: ConceptBase is a deductive and object-oriented database management system based on Datalog rather than SQL. It stores all factual information in a single flat data structure called P-facts. On top of that deductive rules, integrity constraints, and queries are defined to capture the semantics of the application domain. The main application domain of ConceptBase is conceptual modeling, model management, and meta modeling.
