What must structures know?

The correct answer emphasizes that structures in OutSystems must have both their name and information regarding their public status. In OutSystems, structures are used to define complex data types that can be reused throughout an application. Knowing the name of a structure is vital because it serves as the identifier that allows developers to reference and utilize the structure within their logic.

Additionally, awareness of the public status is crucial as it determines whether that structure can be accessed outside of the module in which it is defined. If a structure is public, it can be used by other modules, which is essential for sharing data across different parts of an application. If a structure is not defined correctly regarding its accessibility, it can lead to confusion and limit the reusability of the data type.

This duality of information ensures that developers can effectively manage both the identity and the scope of their structures, allowing for clearer, more maintainable application design.
