Which mechanism helps ensure consistent data flow in OutSystems mobile applications?

The correct choice emphasizes the importance of data preparation logic in maintaining a consistent data flow within OutSystems mobile applications. Data preparation logic is crucial because it acts as a centralized point where data can be processed, transformed, and prepared according to specific requirements before it is presented to the user interface. This ensures that regardless of how or when data is accessed, it maintains integrity and adheres to the application's business rules.

By using data preparation logic, developers can create a uniform method to handle data retrieved from various sources, whether it's local databases or external APIs. This allows for the implementation of validation, filtering, and sorting operations that ensure the data presented to the user is accurate and relevant. Ensuring consistent data flow helps in improving user experience and maintaining application performance by minimizing redundant operations and establishing a clear data structure.

In contrast, global variables serve as shared data points, but their management can lead to unpredictability and potential conflicts if not handled carefully. Screen actions are tied to specific UI elements and do not provide the same overarching control over data flow across the entire application. REST endpoints are instrumental for external data integration but do not intrinsically manage data flow within the application. Therefore, data preparation logic distinctly stands out as the mechanism that effectively ensures consistent and reliable data management
