What JDBC 3.0 features matter? Are many developers storing XML data directly in the database? On behalf of data connectivity company DataDirect Technologies, we recently emailed a small group of TSS subscribers to take part in a survey on their JDBC and XML usage habits. The results were interesting enough that we decided to publish them here for everyone's benefit. This is the first of many more surveys to come, which will hopefully be useful to the community.
If you have any ideas for surveys, please drop us a line and let us know!
