What does pattern inheritance describe in Pega?

Pattern inheritance in Pega primarily describes the relationship between parent and child classes in the context of class structures. This concept is essential for understanding how classes relate to each other within Pega's architecture.

When discussing pattern inheritance, it reflects how classes can inherit characteristics and behaviors from their parent classes, creating a hierarchy that promotes reusability and consistency in applications. This inheritance enables a child class to utilize the properties, methods, and rules defined in its parent class, thereby allowing for a streamlined development process and minimizing redundancy.

The other options focus on different aspects of Pega's architecture and functionality. The first option addresses the functional relationship explicitly rather than the broader business relationship represented by pattern inheritance. The third option relates to external vendor applications, which are not connected to the intrinsic class hierarchy. The last option discusses user roles, which pertain to security and access within the application rather than the structural relationships of class inheritance. This clarifies the specific relevance of pattern inheritance in defining class relationships and building effective applications in Pega.
