# Internal Architecture

The internal directory contains the core business logic of the application:

- [internal/model/](mdc:internal/model): Data models and domain entities
- [internal/service/](mdc:internal/service): Business logic services
- [internal/storage/](mdc:internal/storage): Data persistence layer
  - [internal/storage/dao/](mdc:internal/storage/dao): Database access objects 
  - [internal/storage/cache/](mdc:internal/storage/cache): Redis cache implementation

The application follows a layered architecture with clear separation between:
1. HTTP handlers (in api/)
2. Business logic (in internal/service/)
3. Data access (in internal/storage/)

This design promotes maintainability and testability by decoupling components.
