/**
 * OpenMDM Database Schema Definition
 *
 * This schema defines the structure for MDM data storage.
 * Database adapters implement this schema for their specific ORM/database.
 *
 * Tables:
 * - mdm_devices: Enrolled devices and their state
 * - mdm_policies: Device policies and configurations
 * - mdm_applications: Registered applications for deployment
 * - mdm_commands: Command queue for device operations
 * - mdm_events: Event log for device activities
 * - mdm_groups: Device grouping for bulk operations
 * - mdm_device_groups: Many-to-many device-group relationships
 * - mdm_push_tokens: FCM/MQTT push notification tokens
 * - mdm_app_deployments: App-to-policy/group deployment mappings
 * - mdm_app_versions: App version history for rollback support
 * - mdm_rollbacks: Rollback operation history and status
 * - mdm_webhook_endpoints: Outbound webhook configuration
 * - mdm_webhook_deliveries: Webhook delivery history
 * - mdm_tenants: Multi-tenant organization isolation
 * - mdm_roles: RBAC role definitions
 * - mdm_users: User accounts for authorization
 * - mdm_user_roles: User-role mapping
 * - mdm_audit_logs: Compliance and audit trail
 * - mdm_scheduled_tasks: Scheduled task definitions
 * - mdm_task_executions: Task execution history
 * - mdm_message_queue: Persistent push message queue
 * - mdm_plugin_storage: Plugin state persistence
