OpenEMR integration with proprietary PM

We would like to integrate OpenEMR with our proprietary, web-based practice management system (PM). Is that permissible providing that we only access the MySQL tables directly?

No takers? After reading some additional posts, it seems that we can connect Open-EMR with proprietary systems provided that the interface software between the two is GPL’d. Can anyone confirm. healthbiller.com is a very affordable, load-based PM.

hi @healthbiller, gnu.org has many resources like this in their faq that seems to address your question:
