Abstract : Studies were made of the prototype GLUE/NAIL system which is a deductive database system, techniques for optimizing constraint maintenance in a distributed environment, approaches to nonmonotonic reasoning in databases, efficient main- memory algorithms for essential database operations, especially join, multway join and transitive closure, the problem of maintaining an instantiated view of data, magic-sets implementation techniques, theory of logic programs, and object-oriented versus deductive database approaches.
