Torsten Bittner works as a software engineer in Information Management, IBM Software Group. He carries a diploma degree in computer science from the University of Rostock, Germany. His development responsibilities include the Rational Data Architect mapping editor discovery and the query generation component.

Summary:  You can use IBM® Rational® Data Architect to define data mappings. When working with large schemas, it can be very cumbersome to manually create mappings. Rational Data Architect offers a discovery component to semi-automatically identify potential mappings. This tutorial provides an introduction to the relationship discovery component of Rational Data Architect.

Summary

In this tutorial, you learned how to use the Rational Data Architect discovery component to discover schema relationships.

You can now invoke several metadata-driven and data-driven algorithms to discover similarities of schemas. You created your own glossary model and used it to discover similarities using abbreviations and synonyms. You configured discovery to use data samples and invoked the signature algorithm to discover similarities of data.

The Rational Data Architect relationship discovery component helps to significantly reduce the time to create complex mappings in the Rational Data Architect mapping editor.
