## Анализ домена
|
||||
|
||||
### 1. Domain Identification
|

# Domain Analysis для E-commerce Platform
|
||||
|
||||
## Core Domains
|
||||
- **User Management**: управление пользователями, аутентификация, авторизация
|
||||
- **Product Catalog**: каталог товаров, категории, поиск
|
||||
- **Order Management**: обработка заказов, управление состоянием
|
||||
- **Payment Processing**: обработка платежей, интеграция с платежными системами
|
||||
- **Inventory Management**: управление запасами, резервирование товаров
|
||||
|
||||
## Supporting Domains
|
||||
- **Notification Service**: отправка уведомлений
|
||||
- **Analytics Service**: сбор и анализ данных
|
||||
- **Recommendation Service**: рекомендации товаров
|
||||
- **Review Service**: система отзывов
|
||||
|
||||
## Generic Domains
|
||||
- **Logging Service**: централизованное логирование
|
||||
- **Monitoring Service**: мониторинг системы
|
||||
- **Configuration Service**: управление конфигурацией
|
||||
```
