Schema mapping generation in the wild

作者:

Highlights:

• A dynamic programming algorithm searches a space of mappings for a set of relations.

• The source relations are merged on the basis of relational metadata and profile data.

• An inference mechanism for propagating profile data without data materialization.

• A fitness function for comparing candidate mappings using inferred profiling data.

• A method that populates a multi-relation target schema with constraints.

• An empirical evaluation on real-world and (benchmark) synthetic datasets.
