What are the main components of a Pega application?

The main components of a Pega application include Processes, Data, User Interface, Integrations, and Decision Rules.

Processes refer to the workflows and the way tasks are managed within the application, facilitating the flow of work from one step to another. Data is critical as it defines the information that the application will manage and utilize throughout its processes. The User Interface is the point of interaction for users, where they can input data and interact with the application. Integrations enable the application to communicate and share information with external systems, enhancing its capabilities. Finally, Decision Rules are essential in determining the course of action based on specific conditions, leading to effective decision-making within processes.

These components work together to create a robust framework that supports the application's functionality and user engagement. Other options may focus on narrower aspects or functionalities, but B encompasses the comprehensive elements that form the backbone of a Pega application.
