Though wary of re-igniting the discussion (informative and lively though it has been), I wonder how this relates to the HL7 RIM model (look up RIMBAA) - as I (only partially) understand it this is using the RIM approach, EAV-like, for the data persistence as well as message definition.
Have people used the RIM approach and if so, how did it work in practice?
I have a system to design that won't directly be using healthcare data (so no HL7 use as such) - would anyone recommend for or against using a RIMBAA approach?

RIMBAA, is that just a proposal for how to model a healthcare related data warehouse, or an operational database?

I might be getting the wrong end of the stick, but I interpret it as an approach using the RIM design as a working database design - expressing it in SQL Server.
