// - 2026-05-22: Phase 1 data model for migration architecture refactor
# Data Model: ADR-028 Migration Architecture Refactor
## New Tables (SQL Delta Required — ADR-009)
### tags
```sql
CREATE TABLE tags (
id INT PRIMARY KEY AUTO_INCREMENT,
public_id CHAR(36) NOT NULL UNIQUE, -- UUIDv7 (ADR-019)
project_id INT NULL REFERENCES projects(id) ON DELETE CASCADE,
tag_name VARCHAR(100) NOT NULL,
color_code VARCHAR(30) DEFAULT 'default',
description TEXT,
created_by INT REFERENCES users(id),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
deleted_at TIMESTAMP NULL,
UNIQUE KEY uq_tag_project (project_id, tag_name)
);
```
### correspondence_tags
```sql
CREATE TABLE correspondence_tags (
correspondence_id INT NOT NULL REFERENCES correspondences(id) ON DELETE CASCADE,
tag_id INT NOT NULL REFERENCES tags(id) ON DELETE CASCADE,
is_ai_suggested BOOLEAN DEFAULT FALSE,
confidence DECIMAL(4,3) NULL, -- AI confidence score (0.0001.000)
created_by INT REFERENCES users(id),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (correspondence_id, tag_id)
);
```
## Existing Tables (Updated by this Feature)
### import_transactions (เก็บถาวร — Audit Trail)
```sql
-- ตารางนี้มีอยู่แล้วใน migration SQL
-- เพิ่ม index สำหรับ audit queries:
CREATE INDEX idx_import_transactions_batch ON import_transactions(batch_id);
CREATE INDEX idx_import_transactions_doc ON import_transactions(document_number);
```
### migration_review_queue (Drop หลัง Gate #3)
| Column | Type | Notes |
|--------|------|-------|
| `id` | INT AUTO_INCREMENT PK | — |
| `batch_id` | VARCHAR(50) | FK migration_progress |
| `document_number` | VARCHAR(100) | จาก Excel |
| `temp_attachment_id` | VARCHAR(36) | UUID — cleaned up หลัง commit หรือ 24h |
| `ai_job_id` | VARCHAR(36) NULL | BullMQ job ID — **เพิ่มโดย SQL delta** `2026-05-22-alter-migration-review-queue.sql` (ไม่มีใน 03-04 migration SQL เดิม) |
| `ai_confidence` | DECIMAL(4,3) | 0.0001.000 |
| `ai_summary` | TEXT | — |
| `suggested_tags` | JSON | `[{name, is_new, confidence}]` |
| `status` | ENUM('PENDING','APPROVED','REJECTED','ERROR') | — |
| `reviewed_by` | INT NULL | FK users(id) |
| `reviewed_at` | TIMESTAMP NULL | — |
## BullMQ Job Types (New)
### `migrate-document` (ai-batch queue)
**Input payload:**
```typescript
interface MigrateDocumentJobPayload {
tempAttachmentId: string; // UUID ของ temp file
documentNumber: string;
title: string;
existingTags: TagOption[]; // project tags สำหรับ AI ใช้ประกอบ
systemCategories: string[]; // categories จาก /api/meta/categories
batchId: string;
}
```
**Output (stored in job result):**
```typescript
interface MigrateDocumentJobResult {
isValid: boolean;
confidence: number; // 0.01.0
category: string;
summary: string;
suggestedTags: {
name: string;
description: string;
isNew: boolean;
confidence: number;
}[];
detectedIssues: string[];
ocrMethod: 'fast-path' | 'slow-path';
processingTimeMs: number;
}
```
### `cleanup-temp-files` (ai-batch queue — Scheduled)
รัน Scheduled ทุก 1 ชั่วโมง — ลบ temp attachments ที่:
- `is_temporary = TRUE`
- `created_at < NOW() - INTERVAL 24 HOUR`
- ไม่มี `committed_at` (ยังไม่ถูก commit)
## Entity Relationships
```
projects (1) ──── (N) tags
tags (N) ──── (N) correspondences [through correspondence_tags]
migration_review_queue (1) ──── (1) import_transactions
migration_review_queue.temp_attachment_id → attachments.public_id
```
## State Transitions: Migration Review Record
```
