| Dimensional Warehouse Model Data Model |
| Description | A path through the study that describes what activities the study subject or experimental unit will be involved in as they pass through the study. For example: A study could have 2 arms named IV-Oral and Oral-IV. The name IV-Oral reflects a path that passes through IV treatment, then Oral treatment. |
