Final answer:
It is true that setting up data transforms with default values in a parent class and specific values in subclasses improves maintainability by leveraging the inheritance feature in object-oriented programming.
Step-by-step explanation:
The question relates to the practice of organizing and optimizing data transforms in a hierarchical class structure, which is often used in object-oriented programming and data modeling. The statement made in the question is True. You can indeed set up data transforms such that common default values are established in a parent class (such as a claim class), and then more specific values for subclasses. This method leverages the concept of inheritance, allowing subclasses to inherit common properties from the parent class and override them as necessary. Implementing data transforms in this way enhances maintainability because it reduces redundancy and allows changes to be made in one place rather than in multiple subclass specific data transforms.
