The clinical spine — every entry belongs to a form.

| `form` | openEHR | defines this table |

An ENTRY-derived table (an observation, evaluation, instruction or action) is always recorded on a form, which carries the patient and encounter context for everything on it. Deleting a form cascades to every entry recorded against it.

`patient_id` and `encounter_id` are plain `uuid` columns here and gain their foreign keys at the very end of the apply order, because `form` is created before the administrative tables exist. A build without an administrative Patient or Encounter leaves them unconstrained and says so in the compile report.

## Columns

| Column | Type | Null | Description | Source |
|---|---|---|---|---|
| `id` | `uuid primary key` | no | Primary key. | — |
| `template_id` | `text` | no | Identifier of the form template this was captured with. | — |
| `patient_id` | `uuid` | yes | Patient the form was recorded for; foreign key added at the end of the apply order. | — |
| `encounter_id` | `uuid` | yes | Encounter the form was recorded in; foreign key added at the end of the apply order. | — |
| `name` | `text` | yes | Display name of the form. | — |
| `created_at` | `timestamptz` | no | Row creation timestamp. | — |
| `updated_at` | `timestamptz` | no | Row update timestamp; maintained by the application. | — |
| `created_by` | `text` | no | Actor who created the row. | — |
| `updated_by` | `text` | no | Actor who last updated the row. | — |
