PERSONAL KNOWLEDGE ON THIS: READ READ READ I am Epic Certified and attended the Epic University in Madison Wisconsin in 2014. I configured the applications back end for Hospitals. I did not work for Epic. The university is WILD and I have MANY photos of it, Stairway To Heaven, Treehouse Conference Room, Wild Wall Murals, Employee Theater (Full size like AMC et al.) Crazy statues/Art the place is insane. Totally insane. This tech company controls 3/4 of ALL YOUR HEALTHCARE DATA. Gets deeper when you go into the new Meaningful USe regulations, all the mandatory questions hospitals and clinics MUST ASK on your personal life/demographics not health related…. The database for the app is built on an old MUMPS DB and uses simple SQL Calls to build profiles and projects them to a GUI for end users but the data contained is MASSIVE. UTTERLY MASSIVE.
