What is the purpose of a class in a Pega application?

In a Pega application, the purpose of a class is to organize and provide reusability of rules. Classes act as containers for rules and facilitate the inheritance of those rules, allowing developers to create a structured framework where common functionalities can be defined and inherited by subclasses. This organization not only promotes consistency across the application but also supports the development of modular and maintainable code.

By using classes, developers can leverage the concept of rule resolution, where Pega selects the most appropriate rule to execute based on the specific context of a request. This hierarchy of classes enhances the system's scalability and efficiency, ultimately leading to a more streamlined development process.

User authentication, session data management, and performance metrics are important aspects of application functionality but are not directly handled by classes in Pega. Instead, these concerns are addressed through other components and functionalities within the Pega platform.
