Schema Evolution publication categorizer

Merging and coalescing data from multiple and diverse
sources into different data formats continues to be an important
problem in modern information systems. Schema
Matching, the process of matching elements of a source
schema with elements of a target schema, and Schema Mapping,
the process of creating a query that maps between two
disparate schemas, are at the heart of data integration systems.
We demonstrate Clio, a semi-automatic schema mapping
tool developed at the IBM Almaden Research Center.
In this demonstration we showcase Clio’s mapping engine
that allows mapping to and from relational and XML
schemas, and takes advantage of data constraints in order to
preserve data associations.
