Open MRS is breaking the concept dictionary approach at many places in  
there data structure. Look e.g. at the personal data - all data to the  
patient's name is stored in one table, all address data and so on.

A conceptual approach for personal data wouldn't make sense as naming  
conventions or the way locations are addressed don't change very often.

On the other hand, as far as I understood the database scheme of GNUmed,  
FNUmed seems to use a concept dictionary approach where it is sensibel -  
for storage of encounters for exyample, but without making a lot of fuzz  
about it.

OpenMRS would habve been handy in 2000, as you started work - If I'm not  
mistaken, it would be "only" necessary to write a GUI for OpenMSR (and  
billing modules, and national form handling modules, and letter modules  
and and and) to get an working EMR, thus skipping most of the work you had  
to do in the beginning constructing database concepts from scratch -  
without the manpower and financing of openMSR!

Now, OpenMRS might give some good ideas, and help to polish the database  
structure.
