What is one method for handling exceptions in OutSystems?

The method of handling exceptions in OutSystems through the use of handler flows is significant because it allows developers to gracefully manage errors that occur during the execution of actions in a mobile application. Handler flows are specifically designed to catch exceptions, enabling the application to respond appropriately, whether that means logging the error, displaying a user-friendly message, or taking an alternative route in the business logic.

A handler flow is connected to a particular action and activates when an exception is thrown. This ensures that the main flow of the application remains stable and provides a better user experience by preventing the application from crashing. By using handler flows, developers can define specific recovery processes tailored to different types of exceptions, leading to more resilient applications.

The other methods mentioned do not primarily serve the purpose of exception handling. Implementing static variables pertains to managing state and data storage, creating non-functional requirements focuses on the quality attributes of the system, and optimizing database queries is related to performance improvements. None of these options provide a framework for directly handling exceptions that may arise during application execution.
