The logical model behind each table in the OMOP CDM is displayed as a TypeScript-like type definition. You can view the description of each column by clicking on the purple links. The inverse relationships are added automatically and displayed in light purple. You can navigate to the referenced tables by following the blue links.
I've also added a few minor fixes to the model.
