It can be also seen as a deductive database
for reasoner, using a rule language for rule-based generation of new facts.
As a result, a restricted form of Prolog without function symbols called Datalog (with negation), with a well-defined declarative semantics based on the work in logic programming, has been widely accepted as the standard deductive database
language [Ullman 1989a; Ceri et al.
A deductive database
system combines the multiple file handling, concurrency, security, and recovery aspects of database systems with the logic-based reasoning, in terms of recursive rules, of logic programming.
Another way to understand the memoing evaluation strategy was developed in the deductive database
community, and goes by the name of Magic [1, 2, 27, 28, 29, 36].
In a deductive database
, a theory would be marked as a set of rules that can be applied against the data.
However, the knowledge bases (which contain deductive rules and/or semantic information such as the conceptual hierarchy among data) in existing deductive database
systems can only be built up manually with known technology.

He worked in deductive databases
, nonmonotonic reasoning, and knowledge representation and reasoning in the past.
Under the terms of the agreement HIGHFLEET's ontology-based deductive databases
will be combined with fluidOps' open platform for intelligent information management, Information Workbench, to provide customers with systems that not only efficiently answer high-value queries but enable extensive visual exploration.
Editorial will cover such topics as deductive databases
, data integration and exchange, data mining, database design and tuning, storage, data models and data cleaning and information extraction.
