What forms the basis of the application's rule organization in Pega?

The class hierarchy and class definitions are fundamental to how rules are organized within a Pega application. In Pega’s architecture, applications are built around a class structure, which follows an object-oriented approach. Each class can contain rules such as flows, user interfaces, data types, and decision rules, all of which inherit properties from their parent classes.

This hierarchical organization allows for efficient reuse of rules through inheritance, enabling developers to create more streamlined and maintainable applications. It also facilitates the separation of concerns within the application, ensuring that different components (such as user interface, process logic, and data management) can be managed effectively based on their respective class definitions.

Understanding the class hierarchy is crucial for anyone working in Pega, as it not only impacts how rules are applied but also influences how data is structured and how various elements of the application interact with each other.
