Deductive and Object-Oriented Databases: Third International Conference, DOOD '93, Phoenix, Arizona, USA, December 6-8, 1993. Proceedings [Paperback]

This volume contains the proceedings of the ThirdInternational Conference on Deductive and Object-OrientedDatabases. Its central tenet is that the object-oriented anddeductive paradigms for modeling, organizing, and processingdata complement each other, rather than competing, and thatproblems involving massive volumes of complex data can bestbe solved by integrating the best of both approaches.Central questions in the area are:- How do we design a tool that presents the best of theobject-oriented and declarative ideas?- How can the users of this tool express their problems in acombination of declarative and procedural features?The volume includes 29 papers that contribute towardsanswering these questions.Treating programs as objects: The computational proxy experience.- Foundations of aggregation in deductive databases.- The differential fixpoint operator with subsumption.- Datalog with non-deterministic choice computes NDB-PTIME.- A deductive and object-oriented approach to a complex scheduling problem.- On the logical foundations of schema integration and evolution in heterogeneous database systems.- Explaining program execution in deductive systems.- A logic for rule-based query optimization in graph-based data models.- Specifying rule-based query optimizers in a reflective framework.- Semantic query optimization in deductive object-oriented databases.- Research in deductive and object-oriented databases.- An implementation overview of the Aditi deductive database system.- Negation and aggregates in recursive rules: the LDL++ approach.- IsaLog?: A deductive language with negation for complex-object databases with hierarchies.- On efficient reasoning with implication constraints.- Bottom-up query evaluation with partially ordered defaults.- An extension of path expressions to simplify navigation in object-oriented queries.- Query classes.- Database updating revisited.- Super-key classes for updating materilS\
