Résumé
This book provides an overview about the state-of-the-art solutions and the most recent advances in schema matching and mapping, both recognized as key areas of metadata management. Tasks involving metadata are indeed pervasive in databases and information systems and include schema evolution, schema and ontology integration and matching, XML message mapping, as well as data migration and data exchange. While research on these complex problems has been performed since several decades, we have witnessed significant progress especially in the last decade. In particular, research addressed the metadata problems in a more abstract and generic way rather than focusing on specific applications and data models. A cornerstone of this new line of research is the notion of schema mappings, i.e., expressive mappings interrelating schemas (or other metadata models such as ontologies). Furthermore, powerful operators to manipulate schemas and mappings (e.g., matching and merging of schemas or composition of mappings) have been investigated for solving various kinds of metadata-related tasks.
Many steps have been performed towards the various goals of matching and mapping different kinds of design artifacts (i.e. a relational schema, a web site, or a data mart), thus motivating a flurry of recent research, which we survey in this book.

The book consists of ten comprehensive chapters grouped within three parts: large-scale and knowledge-driven schema matching, quality-driven schema mapping and evolution, and evaluation and tuning of matching tasks.

The book provides:

1. a comprehensive survey of current and past research on schema matching and mapping;
   
2. an up-to-date source of reference about schema matching and mapping, schema and ontology evolution, schema merging and matching and mapping
   evaluation;
   
3. scholarly written chapters enabling a learning experience to both experts and non-experts whenever they would like to enhance their knowledge or build it from scratch; the chapters have been conceived in such a way to be readable individually or altogether by following the book table-of-contents.
