## Advanced Laravel Tip: Repository Pattern Implementation

Implement the Repository Pattern to decouple your business logic from data access logic. Create interfaces that define methods for accessing data, then concrete repository classes that implement these interfaces. This abstraction makes your application more testable, maintainable, and allows you to switch data sources without modifying business logic.

```php
// Define interface
interface UserRepositoryInterface {
    public function getAll();
    public function findById($id);
    public function create(array $data);
}

// Implement for Eloquent
class EloquentUserRepository implements UserRepositoryInterface {
    public function getAll() {
        return User::all();
    }
    
    public function findById($id) {
        return User::find($id);
    }
    
    public function create(array $data) {
        return User::create($data);
    }
}

// Bind in service provider
$this->app->bind(UserRepositoryInterface::class, EloquentUserRepository::class);
```
