JDBC data extraction 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.
