Pega Platform divides rules into classes based on their re-usability inside an application. Each cluster is referred to as a class. Each application is made up of three different class kinds.
The Data Class : This class specifies the rules that govern the use of data types and objects.
The Integration Class : This class comprises rules that spell out how the application interacts with external services and resources such as customer databases and 3rd party servers.
The Work Class : This class consists of data items, interfaces, and other resources that govern the processing of test cases.
