Viac o knihe
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.
