Semantics for Non-Monotone Queries in Data Exchange and Data Integration

pdf-format:
ch06-hernich.pdf (0.6 MB)

Abstract

A fundamental question in data exchange and data integration is how to answer queries that are posed against the target schema, or the global schema, respectively. While the certain answers semantics has proved to be adequate for answering monotone queries, the question concerning an appropriate semantics for non-monotone queries turned out to be more difficult. This article surveys approaches and semantics for answering non-monotone queries in data exchange and data integration.
