[Chameleon] Visualize data from other data source in mapfile

[Paul Spencer]

I believe you can join a shapefile to an external database via the 
mapfile (I don't know how to do this, best to ask on the mapserver 
mailing list).

Cheers

I also have another data source (e.g. dbf-file, MySQL, MS Acces, etc.) in which this code is also present together with some more information attached to it. Is it possible to visualize this external information in the map to classify the polgyon layer based upon expressions that use the information from the additional data source? In other words, if it possible to join this information for visualization, so that when the other data source is update, the map in the Chameleon application is also automatically updated?
