What do constraints rules define in Pega?

Constraints rules are designed to define the comparison relationships among property values in Pega applications. This is crucial for establishing conditions under which certain operations or processes can occur within an application. When you utilize constraints, you can enforce specific business rules, such as ensuring that one value should not exceed another or that certain fields must align with a predetermined format or criteria.

This capability supports data integrity and ensures that the application behaves in a predictable manner. For instance, if one property must always be greater than another, a constraint rule can be applied to enforce this relationship. This allows developers to create conditions that maintain logical and consistent data usage across the application, ultimately enhancing performance and reliability.

The other options relate to different aspects of Pega’s functionality; application logic involves the broader rules governing user interactions and processes, user interface layout pertains to how elements are displayed visually to users, and security measures for data access involve configurations that protect data within the application. Each plays a distinct role, but they do not encapsulate the specific purpose of constraints rules like defining property comparison relationships does.
