Our good friends at MySQL and Pentaho are hosting a webinar about ETL for MySQL using Pentaho Kettle. 

ETL is a multipurpose technology, from straight data integration to data migration to reporting systems.  Kettle is primarily used in building Data Warehouse/Data Marts but can also be used for doing other useful MySQL admin tasks. 

Matt Casters and Lance Walter will give you the low down on Kettle:

I recommend it, even if you’re not interested in MySQL.  You’ll be surprised that an Open Source ETL tool is so visual and easy to use you may consider it for all kind of tasks.
