# Migration System Integration - Seller Marketing Module

## Overview
The Seller Marketing Module database schema has been successfully integrated with the existing UserFrosting migration system. This provides a standardized approach to database management using the established `php conductor.php run` command.

## Migration Files Created

### Global Database Migration
**File**: `userfrosting/migrations/input/20250109_create_seller_marketing_queue.json`
- **Target**: `kiosk_buykiosk` (global database)
- **Creates**: `seller_marketing_queue` table
- **Purpose**: Central outgoing message queue for all stores

### Store-Level Database Migrations
All store-level tables use the `"database": "{{store}}"` pattern to apply to all store databases:

#### 1. Messages Table
**File**: `userfrosting/migrations/input/20250109_create_seller_marketing_messages.json`
- **Creates**: `seller_marketing_messages` table
- **Purpose**: Message templates with variables and metadata

#### 2. Triggers Table
**File**: `userfrosting/migrations/input/20250109_create_seller_marketing_triggers.json`
- **Creates**: `seller_marketing_triggers` table
- **Purpose**: Automated trigger configurations
- **Foreign Keys**: References `seller_marketing_messages`

#### 3. Blasts Table
**File**: `userfrosting/migrations/input/20250109_create_seller_marketing_blasts.json`
- **Creates**: `seller_marketing_blasts` table
- **Purpose**: One-time SMS blast campaigns
- **Foreign Keys**: References `seller_marketing_messages`

#### 4. Analytics Table
**File**: `userfrosting/migrations/input/20250109_create_seller_marketing_analytics.json`
- **Creates**: `seller_marketing_analytics` table
- **Purpose**: Performance tracking and reporting
- **Foreign Keys**: References `seller_marketing_triggers`, `seller_marketing_blasts`, `seller_marketing_messages`

#### 5. Customer Log Table
**File**: `userfrosting/migrations/input/20250109_create_seller_marketing_customer_log.json`
- **Creates**: `seller_marketing_customer_log` table
- **Purpose**: Complete audit trail of customer communications
- **Foreign Keys**: References `seller_marketing_triggers`, `seller_marketing_blasts`, `seller_marketing_messages`

#### 6. Sample Data
**File**: `userfrosting/migrations/input/20250109_insert_seller_marketing_sample_messages.json`
- **Inserts**: Sample message templates
- **Includes**: 4 pre-built messages (Welcome Back, Birthday Greeting, New Arrivals, Thank You)

## Migration Features

### JSON Schema Structure
Each migration file follows the established pattern:
```json
[
  {
    "type": "create_table|alter_table|insert",
    "description": "Human-readable description",
    "database": "{{store}}|kiosk_buykiosk|specific_db_name",
    "check_query": "Query to check if migration is needed",
    "sql": "SQL statement to execute"
  }
]
```

### Built-in Safety Features
- **Check Queries**: Prevent duplicate table creation
- **Migration Logging**: Tracks applied migrations in `kiosk_buykiosk.migration_log`
- **Store Iteration**: Automatically applies to all active stores
- **Error Handling**: Comprehensive error reporting and rollback
- **Idempotent**: Safe to run multiple times

## Usage Instructions

### Running the Migrations
```bash
cd /path/to/buyerkiosk-web
php userfrosting/conductor.php run
```

### Migration Process
1. **Global Tables**: Creates `seller_marketing_queue` in `kiosk_buykiosk`
2. **Store Tables**: Creates all 5 store-level tables in each store database
3. **Sample Data**: Inserts 4 sample message templates
4. **Logging**: Records all successful migrations in `migration_log`

### Verification
After running migrations, verify by checking:
- **Global**: `kiosk_buykiosk.seller_marketing_queue` exists
- **Store**: All 5 tables exist in store databases (e.g., `kiosk_ou00`)
- **Data**: Sample messages exist in `seller_marketing_messages`
- **Logs**: Migration entries in `kiosk_buykiosk.migration_log`

## Integration Benefits

### 1. Consistency
- Uses established migration patterns
- Follows existing naming conventions
- Integrates with current logging system

### 2. Safety
- Prevents duplicate migrations
- Comprehensive error handling
- Rollback capabilities through logging

### 3. Automation
- Applies to all active stores automatically
- No manual store-by-store setup required
- Idempotent execution

### 4. Maintenance
- Centralized migration management
- Version-controlled schema changes
- Audit trail of all changes

## Database Schema Overview

### Global Database (kiosk_buykiosk)
```sql
seller_marketing_queue
├── id (PK)
├── store_id (FK → stores.id)
├── phone
├── message
├── message_type (trigger|blast)
├── trigger_id, blast_id
├── created_at, send_at, sent_at
├── status (pending|sent|failed|cancelled)
├── provider (vonage|twilio)
├── provider_id, error_message
├── attempts, max_attempts
└── priority
```

### Store Databases (kiosk_{typeNum})
```sql
seller_marketing_messages
├── id (PK)
├── name, content, variables
├── created_at, updated_at
├── active, character_count, sms_count
└── category

seller_marketing_triggers
├── id (PK)
├── name, type, message_id (FK)
├── status, config
├── created_at, updated_at
├── expire_date, last_processed
├── processing_frequency
├── time_frame, time_random
└── active_days

seller_marketing_blasts
├── id (PK)
├── name, message_id (FK)
├── criteria, scheduled_at
├── created_at, started_at, completed_at
├── status, recipient_count
├── sent_count, failed_count

├── response_content, conversion_tracked
└── created_at
```

## Model Classes Integration

The existing model classes (`SellerMarketingMessage`, `SellerMarketingTrigger`, `SellerMarketingBlast`, `SellerMarketingQueue`) work seamlessly with the migrated database schema. No changes to the models are required.

## Next Steps

1. **Run Migrations**: Execute `php userfrosting/conductor.php run`
2. **Verify Installation**: Check tables and sample data
3. **Begin Phase 2**: Start implementing API endpoints and controllers
4. **Test Integration**: Ensure models work with migrated schema

## Rollback Strategy

If rollback is needed:
1. Drop all created tables manually
2. Remove migration entries from `kiosk_buykiosk.migration_log`
3. Tables to drop:
   - Global: `seller_marketing_queue`
   - Store: `seller_marketing_messages`, `seller_marketing_triggers`, `seller_marketing_blasts`, `seller_marketing_analytics`, `seller_marketing_customer_log`

## Migration Log Entries

After successful execution, the following entries will appear in `kiosk_buykiosk.migration_log`:
- `20250109_create_seller_marketing_queue` (global)
- `20250109_create_seller_marketing_messages` (per store)
- `20250109_create_seller_marketing_triggers` (per store)
- `20250109_create_seller_marketing_blasts` (per store)
- `20250109_create_seller_marketing_analytics` (per store)
- `20250109_create_seller_marketing_customer_log` (per store)
- `20250109_insert_seller_marketing_sample_messages` (per store)

This integration provides a robust, maintainable foundation for the Seller Marketing Module that follows established patterns and can be safely deployed to production.
