| Dimensional Warehouse Model Data Model |
| Description | A subject that is potentially available for research studies. A patient study subject is also known as a research version of the patient, housing none of the patients identifying information. For example: A person who is registered in a study as a recipient of an investigational product or as a control. Individuals who are being screened for studies. Individuals participating in observational or other studies. A pacemaker. A fuse that can be used in medical devices. A cow. A pen of pigs. A tissue sample from a tissue bank. |
