A classificationof schema mappings and analysis of mapping tools

Frank Legler and Felix Naumann

Schema mapping techniques for data exchange have become popular and useful tools both in research and industry.

The set of correspondences, i.e., the mapping, is interpreted as a data transformation usually expressed as a query. These queries transform data from the source schema to conform to the target schema. They can be used to materialize data at the target or used as views in a virtually integrated system.
