Semantic heterogeneity is concerned with the differences in the meaning and interpretation of similar data objects across the different systems. In loosely coupled database federations, static schema integration may be not feasible and heterogeneity c

To support this rule-based active mechanisms, it is desirable that rules can be taken into account on the conceptual level. Another important reason for focusing on rules is th

In this paper an update calculus is proposed by which updates, constraints and rules are specified and managed within the same formalism. Constraints and production rules

Unfortunately, designing, implementing and evolving applications based on the active database paradigm is still a very difficult task, mostly due to the poor understanding of the semantic issues underlying active rules.
