Summary:  XML is best suited to storing data, so it's inevitable that at some point someone will ask you to pull information from a database and manipulate it as though it were XML. This tutorial will teach you to access a database using JDBC and use SQL to pull information, which you will then use to build an XML Document using a predetermined mapping.

JDBC data extraction summary

Summary

This tutorial discussed the details of connecting to a database using JDBC and extracting data, which was then used to create an XML file. Discussion included making the application generic so that it could be used with any query and any structure. This was accomplished partly through the use of metadata.

The structure of the XML destination file was determined by an XML mapping file. The tutorial also covered the details of reading the mapping file and using it to massage the temporary XML file into the desired structure.
