between the source and target schema elements and these arrows are interpreted as
matchings and translated into a query. The heart of Clio is its incremental matching
engine, which uses information about the matching that is input from a user to infer
and re-rank correspondences. The Clio project has been in development since 1999,
and a product version is now available as part of the Rational Data Architect.

MapForce is part of Altova's XML suite of tools.

Similar to Clio, users can
draw matching correspondences between the source and target schemas and these
are used to automatically generate queries to support data integration. For XML
and database matchings, the matching can be saved as XSLT, XQuery, or generated
as programming language code (e.g., Java). MapForce supports a feature to “auto
connect matching children.” When a parent element is manually connected, children
with the same name are automatically mapped.
Similar to MapForce, the Stylus Studio contains an XML matching tool that sup-
ports visual matching between XML, relational databases, and web service data.
