Explain the role of the DataExtension class in extending SilverStripe’s functionality.

Answer: The `DataExtension` class in SilverStripe allows developers to extend existing data models without modifying the core classes. It enables the addition of new fields, methods, and behavior to existing data objects, thus enhancing functionality while maintaining clean, modular code. By using `DataExtension`, developers can create reusable extensions that can be applied to multiple classes, promoting code reusability and maintainability in SilverStripe applications.
