What is a 'data action' in OutSystems?

A 'data action' in OutSystems is specifically designed to perform operations that interact with the data layer of an application. This includes tasks such as fetching, creating, updating, or deleting data records from a database or any related data source. It serves as a critical component in managing the flow of data within an application, allowing developers to execute operations that retrieve data for display in the user interface or manipulate data based on user interactions.

This choice accurately reflects the primary purpose of data actions within the OutSystems ecosystem, highlighting their role in establishing communication between the application’s user interface and the underlying database or data services. By utilizing data actions, developers can implement data-driven functionalities seamlessly within their applications, making these actions fundamental to the overall architecture.

The other options focus on different functionalities that do not align with the specific definition of a data action. User interface adjustments pertain more to the presentation layer and how an application looks and behaves visually, while security measures involve protecting application resources rather than data manipulation. Application logic, though related, is not confined to data interactions as it encompasses broader functionalities involving decision-making and processes within the application.
