What is a common function of a class in schema design?

In schema design, one of the primary functions of a class is to contain multiple field groups. A class acts as a blueprint for different data entities, grouping together related fields that represent characteristics or attributes of that particular entity. This structure facilitates organized data management and ensures that all relevant attributes are encapsulated under a specific class.

For instance, when designing a class for a customer entity, it would contain field groups for personal information (like name and address), contact information (like phone number and email), and transactional history. This logical separation allows developers to efficiently manage and access the attributes tied closely with the specific class, enhancing data structure integrity and usability.

The other functions, such as defining relationships or mapping data types, are essential aspects of schema design but do not capture the primary role of a class in organizing various fields into coherent groupings that represent a singular concept or entity.
