Sounds like bullshit, work with this data in AI and clinical research etc at HiGHmed.
Define a cohort, identifiy EHRs → export data.
E.g. JSONS or parse into CSV and let the researcher have it.
Response times can take a while this is true.
What is he/she doing with the data ?
I have even an export script laying around btw if you need it.
Its not a fullfletched dataWarehouse thats true missing e.g. the business intelligence layer.
