What are some alternative methods to improve database design when dealing with multiple modules in a PHP application?

When dealing with multiple modules in a PHP application, one alternative method to improve database design is to implement a modular approach by using a database abstraction layer or ORM (Object-Relational Mapping) tool. This allows for better organization and separation of concerns within the application, making it easier to manage and maintain the database schema across different modules.

// Example using an ORM like Eloquent in Laravel

// User model
class User extends Model {
    protected $table = 'users';
}

// Post model
class Post extends Model {
    protected $table = 'posts';
}
