The legacy i2b2 data model is comprised of a central fact table (observation_fact) surrounded by multiple dimension tables (star schema). In the Observation Medical Outcomes Partnership (OMOP) Clinical Data Model (CDM) rather than a central fact table, we have a collection of them distinguished by domain:  procedures, condition, drug, measurement, observation, etc.  In this project, we modify the CRC to run queries against multiple domain fact tables as dictated by the metadata.
