The DataMgr component for simplifying basic database interactions has now reached version 1.0. The component has been in use on production sites for about a year.
Recent changes include a handful of bug-fixes and small improvements (most of which are courtesy of Kenton Gray). One small enhancement is the ability to add "seed data" to a table upon its creation when using loadXML (for more information see the DataMgr documentation and the XML Schema for loadXML).
DataMgr currently supports MS Access, MySQL, PostGreSQL and SQL Server. It is easy to add isupport for other databases as well. I hope to add support for Oracle at some point in the future. I would be willing to help add support for other databases as well.
You can find documentation (including links to other blog entries) and the download for the DataMgr component on the ColdFusion Components page of the Bryant Web Consulting web site.
