I'm guessing a bit, here...

GPC is supposed to align with PCORI CDM; i.e. we're supposed to be able to 
answer queries w.r.t. that data model.

The PCORI CDM doesn't use an EAV table like i2b2, redcap, and similar systems; 
it uses ordinary row modelling. So it has a DEMOGRAPHIC table with columns for 
birth_date, sex, ethinicity (HISPANIC), race, and a few others. So when we 
report results from our i2b2 data, we'll need to construct rows of that form. 
So the PATIENTS query Jim sketched, to me, looks like a projection of "select * 
from CDM.DEMOGRAPHIC" into the i2b2 star schema.

When that's represented as an i2b2 counting query, the results would be a count 
of the number of patients where we have data mapped for all those columns (even 
if the data is some sort of "unknown" or "not recorded" marker). Or it could be 
a PDO query (e.g. for the timeline) and the expected results would be, more or 
less, a PCORI CDM DEMOGRAPHICS table.

Comment (by nathan.wilson):

 Quick Question.  What is the purpose of each test and what are the
 expected/anticipated results for each test in the Milestone_27_TestSQLv4
 document?
