Data Translation - ETL tool

I've been looking for a good data translation and migration tool for use on both static and dynamic data - I often have these issues with my Enterprise Transformation projects. I confess, I still think that Excel and my collection of MS Access scripts are good for many jobs, but today I saw a demo of a really good special purpose tool for 'Extract Transform and Load' activities - and it's open source! The tool is from an outfit called Talend - they have commercial versions and consulting services too. -- Philip Greenwood
