Hello, all in OHDSI community.
I’m a person who is still learning OMOP CDM.
It is really hard to understand for me, but I’ve tried to study it with OMOP CDM Version 5.0 (with VMware Ohdsi-in a box).
In domain, there are some double domains as Condition/Device, Condition/Drug, Condition/Meas, Condition/Obs…etc.
I’m not able to find them searching google or other websites (even wiki)
Does anyone explain them to me if you already know? Also why developers made it?
