Experimental MySQL schema for QWIPU files released

The QWI public use files are very large. Here at the VirtualRDC, we usually use SAS, but occasionally use MySQL. Table definitions and readin programs may come in handy to other users of our data, and we have posted them here. Registered users can access them immediately. New users wishing to access the data can request a login for the site by sending an email to virtualrdc@cornell.edu.
