Hi Seref, From what we've seen in HL7 RIMBAA EAV is rarely embraced wholesale - in practice people (if they use EAV at all) use a mixed RDBMS - EAV approach. RDBMS for its speed and indexing capabilities, EAV for blob-type storage of rarely searched/used data. If you don't need the ultimate flexibility/extendability of EAV, you probably shouldn't use it if only for performance reasons (and as a human it gets hard to understand pretty fast).

Like always, no silver bullits .. I agree one should listen to those that have already built systems within healthcare, and not just theorize about building such systems. The proof of the pudding is in the eating, not in the chewing on the recipe.
