## Implementing Repository Pattern for Database Abstraction

Consider implementing the Repository Pattern in your Laravel applications to abstract database logic away from your controllers. This creates a clean separation of concerns and makes your code more maintainable and testable.

```php
// Create a repository interface
interface UserRepositoryInterface {
    public function all();
    public function find($id);
    public function create(array $data);
}

// Implement the repository
class EloquentUserRepository implements UserRepositoryInterface {
    protected $model;
    
    public function __construct(User $model) {
        $this->model = $model;
    }
    
    public function all() {
        return $this->model->all();
    }
    
    public function find($id) {
        return $this->model->findOrFail($id);
    }
    
    public function create(array $data) {
        return $this->model->create($data);
    }
}

// Bind in a service provider
public function register() {
    $this->app->bind(UserRepositoryInterface::class, EloquentUserRepository::class);
}
```

This makes switching data sources easier and improves unit testing by allowing you to mock the repository.
