Welcome to IOU Digital Library

The book introduces the foundational problem of data integration—providing unified access to heterogeneous data sources—and presents the relational logic approach, a formal framework that enables principled reasoning about schemas, mappings, and queries. It covers key techniques such as query folding, optimization, reformulation, and the use of ontologies, emphasizing cases where integration can be automated efficiently.
