A Decompositional Approach for Computing Least Fixed-Points of Datalog Programs with ,-Counters,applying a set of rules that transform general computation paths into “canonical” ones. We use the method for treating the problem of reachability in the field of Petri nets, thus relating some unconnected results and extending them in several directions.

Memoing Evaluation for Constraint Extensions of Datalog,-down resolution with memoing and the closed form bottom-up evaluation. In this way the top-down evaluation is guaranteed to terminate for all queries for which the bottom-up evaluation terminates. The main advantage of the proposed method is the direct use of the information present in partially in

Maintaining Global Integrity Constraints in Distributed Databases,tes made to the base relations but without accessing all these base relations. In many application areas such as collaborative design, mobile computing and enterprise information systems, total data availability cannot be assumed. Even if all the base data is available, some of it may incur such a h

Implementation and Evaluation of Decision Trees with Range and Region Splitting,es to handling numeric attributes, conventional methods are inefficient if any numeric attributes are strongly correlated. Our approach offers one solution to this problem. For each pair of numeric attributes with strong correlation, we compute a two-dimensional association rule with respect to thes

Constraint databases have recently emerged to deeply integrate data captured by constraints in databases. This paper reports on the development of the first constraint object-oriented database system, CCUBE, a

Our major concern is query optimization in LCDBs. Traditional database approaches are not a
