Abstract

We present the framework of Existential Active Integrity Constraints (EAICs) introduced in [1]. EAICs are a powerful extension of Active Integrity Constraints (AICs), which allow us to express a wide range of constraints used in databases and ontological systems. Specifically, the paper discusses a new definition of founded updates for AICs, presents syntax and semantics for EAICs, and a "representative" set of founded updates for EAICs, called universal, which suffices for query answering.
