We propose a two-pha.se algorithm for physical database design. In phase one the algorithm, for each logical query, losesrules to determine characteristics of a physical design (s...
We introduce a proposal to give argumentation capacity to databases. A database is said to have argumentation capacity if it can extract from the information available to it a set ...
This tutorial presents an overview of the data management issues faced by computer games today. While many games do not use databases directly, they still have to process large am...

This paper examines the problem of adding non-deterministic constructs to a declarative database language based on Horn Clause Logic. We revise a previously proposed approach, the...
Abstract. We study the complexity of consistency checking and query answering on incomplete databases for languages ranging from non-recursive Datalog to disjunctive Datalog with n...
