Focusing on the complexities of data exchange, this work explores how to effectively transform data from a source schema to a target schema while maintaining semantic consistency. It addresses both relational and XML contexts, highlighting key tasks such as schema mappings, target instance materialization, and query rewriting. Additionally, it delves into metadata management, examining operations like schema mapping composition and inverses. The discussion extends to XML-specific challenges, including consistency issues and the need for stricter mapping and query constraints for efficient data handling.

Provides a summary of the key developments of a decade of research into the area of data exchange.

This book constitutes the refereed proceedings of the Second International Workshop on Datalog 2.0, held in Vienna, Austria, in September 2012. The 14 revised full papers presented together with 2 invited talks and 2 invited tutorials were carefully reviewed and selected from 17 initial submissions. Datalog 2.0 is a workshop for Datalog pioneers, implementors, and current practitioners; the contributions aim to bring every participant up-to-date with the newest developments and map out directions for the future.
