DOMAIN Table
The DOMAIN table includes a list of the Domains the Concepts of the Standardized Vocabularies can belong to. A Domain defines the set of allowable Concepts for the standardized fields in the CDM tables. For example, the “Condition” Domain contains Concepts that describe a condition of a patient, and these Concepts can only be stored in the condition_concept_id field of the CONDITION_OCCURRENCE and CONDITION_ERA tables. This reference table is populated with a single record for each Domain and includes a descriptive name for the Domain.
| Field | Required | Type | Description |
|---|---|---|---|
| domain_id | Yes | varchar(20) | A unique key for each domain. |
| domain_name | Yes | varchar(255) | The name describing the Domain, e.g. “Condition”, “Procedure”, “Measurement” etc. |
| domain_concept_id | Yes | integer | A foreign key that refers to an identifier in the CONCEPT table for the unique Domain Concept the Domain record belongs to. |
