What component represents logical structure in OutSystems applications?

In OutSystems, the correct representation of logical structure within applications is found in structures. Structures serve as a way to define complex data types, which can include multiple attributes and even nested structures, thereby allowing developers to create a clear and organized schema for the data used within applications.

The key function of structures is to encapsulate data in a way that reflects its logical organization, making it easier to handle and manage throughout the application. For instance, a structure can represent composite data types such as customer information that might include attributes like name, address, and phone number, each of which can be a different data type. This logical representation is crucial for maintaining data integrity and ensuring that the application behaves as expected when processing this data.

While entities are also important components within OutSystems by representing database tables, they focus on the persistence of data rather than its logical structure for use in the application. Widgets, on the other hand, are used for user interface development and do not inherently represent any data or logical structure. Iterations refer to looping constructs used in logic flows and are not related to the structural representation of data.
