Which component allows developers to maintain design consistency in Pega applications?

The component that allows developers to maintain design consistency in Pega applications is user interface templates. User interface templates provide a standardized way to define the layout, appearance, and behavior of the application's user interface elements. By utilizing these templates, developers ensure that various screens and forms adhere to a cohesive design, making the application more intuitive and visually appealing for users. This consistency is essential in promoting user familiarity with the application and enhancing the overall user experience.

Database management focuses on the storage and retrieval of data rather than the visual presentation of the application. Rulesets are used for organizing rules and managing versioning but do not directly address design consistency. Decision trees are used for making decisions based on conditions but do not contribute to the visual design aspect of the application. Thus, user interface templates stand out as an essential tool for maintaining design consistency within Pega applications.
