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 the SQL/XML query language to transform relational data into XML format. Since it is cumbersome to manually write SQL/XML queries, IBM® Rational® Data Architect simplifies this work by automatically generating SQL/XML queries based on graphically defined mappings. Get an introduction to the SQL/XML generation component of Rational Data Architect.

Summary

In this tutorial, you learned how to use Rational Data Architect to generate SQL/XML queries. You used the mapping editor to graphically define mappings from a relational source schema to an XML target schema. The mapping information was used to generate an SQL/XML query that extracts data from the relational database and populates it in XML form. You executed the generated query and analyzed the resulting XML data.

The tutorial also showed how to use mapping groups to analyze and create joins between multiple source columns. Finally, you added transformation functions to the mapping model.

Rational Data Architect can be used to quickly generate complex SQL/XML queries. The automatic query generation significantly reduces the time it takes to manually create SQL/XML queries.
